We — KH Hussain, CV Radhakrishnan, PK Ashok Kumar and KV Rajeesh — are the copyright holders of TN Joy font. Many of us have worked on free/libre/open source software for years in our spare time and contributed code, design, fonts, documentation, localization and financial support to various free software projects. Our contributions can be found easily on the Web and elsewhere.
A copyright/‘credit’ issue
Immediately after the font ‘TN Joy’ was released to public by Rachana Institute of Typography (RIT), on 2-Oct-2019, Santhosh Thottingal raised a question in a forum with enough number of participants to qualify as a public discussion:
@rajeeshknambiar there are lot (sic) of contributions from me, Kavya in the build scripts, tests, and feature files in https://gitlab.com/rit-fonts/tnjoy/ Consider giving credit.
On 14-Oct-2019, Santhosh followed up again.
@rajeeshknambiar did not reply to my request for giving credits in their font.
Ask hussain sir to give credits for font testing and building framework. Crediting anivar alone is not enough.”
To which Rajeesh responded on 19-Oct-2019, to discuss with all the copyright holders of TN Joy about the issue:
“Noted. I will try to take it up for discussion and let you know.
On 29-Oct-2019, Santhosh again followed up:
അങ്ങനെ എഴുതുകയും ചെയ്യുകയും ചെയ്ത ഫോണ്ടിന്റെ കാര്യങ്ങൾക്ക് ക്രെഡിറ്റ് കിട്ടിയില്ലെന്നാണ് പറയുന്നത് അനിവർ:) sundar, and janayugam fonts. ഇതിൽ രാജാജിയുടെ ഹെൽപ്പൊന്നും വേണ്ട. even @rajeeshknambiar can just fix it
During the first week of Nov-2019 for the summit organized by Kerala Media Academy, all the copyright holders of TN Joy font met and discussed the issue raised by Santhosh.
As free software developers and users, it was not our intention to violate copyright or appropriate credit of another free software developer’s work at all. Not only in intention, but we strived to achieve that in all our projects by acts. So, this accusation came as a surprise to us and we decided to take a deeper look at how this issue originated and what the root cause is, to address it properly.
We did a detailed analysis and documented the following details.
- A Malayalam Unicode font has two essential parts — the Glyphs (അക്ഷരരൂപങ്ങൾ) and the OpenType shaping lookup rules. Unlike Latin fonts, both of these are necessary for proper shaping. The final TTF/OTF/WOFF2 contains both Glyphs and OpenType shaping rules to make a Malayalam Unicode font usable software. Without either, such a software is not usable.
- The Malayalam opentype features (GSUB and GPOS ‘lookup rules’) used in font ‘TN Joy’ developed by Rachana Institute of Typography (RIT) are adapted from that of font ‘Sundar’ which in turn are adapted from feature file of ‘Rachana’.
- To develop the feature file of Rachana over the years, many have contributed including the original author Hussain KH , Suresh P, Santhosh Thottingal, Rajeesh KV, Kavya Manohar et al. .
- Hussain KH invented and implemented the glyph naming conventions (‘k1’ for ‘ ക’, ‘xx’ for ‘ ്’ etc. instead of names like ‘uni0D15’ etc.), which made font featuring highly comprehensible for programming and much easier to maintain. This naming scheme is followed by all fonts maintained by Swathanthra Malayalam Computing (SMC) and RIT. This was also the naming scheme in fonts developed by ATPS and when it was pointed out that those fonts were derived from SMC’s, the immediate change made was renaming the glyphs and lookup rules [2, 3, 4].
- Rajeesh is the original author of lookup rules of SMC’s fonts for revised ‘mlm2’ OpenType specification for Malayalam, and made it possible to support both ‘mlym’ and ‘mlm2’ specification in a single font. This resulted in making a single font work well with Windows XP, Pango/Qt4 era applications and Uniscribe, HarfBuzz era applications .
- In 2015, Santhosh split the comprehensive lookup rules from the Fontforge SFD file of Rachana into a separate feature file, but the copyright statements were not preserved . It is our opinion that removing copyright statements is violation of copyright act (hence a crime) and immoral in the free software world. This is also the root cause for missing copyright in the OpenType lookup rules and build script, of the fonts in question.
- The same lookup rules in 2, 4 and 5 are used and adapted by subsequent fonts developed by SMC and RIT, such as Chilanka, Manjari, Sundar, Gayathri, TN Joy etc. Rajeesh did not claim for credit or copyright when Manjari or Gayathri was released.
With this background,
- Fonts developed, maintained and distributed by both SMC and RIT, specifically its OpenType lookup rules + fontforge based build tool + test cases are at the heart of this issue. This is caused by the change introduced by Santhosh in .
- The copyright holders of TN Joy font were made aware of such ‘credit’ issue — the definition of which Santhosh has not clarified and in RIT’s understanding is sufficient and limited to ‘copyright’. Thanks for bringing light into such a potential legal and moral risk that affects the users and organizations using these fonts.
- RIT would like to acknowledge the copyright of Santhosh Thottingal and Kavya Manohar for the development of ‘Sundar’ and ‘TN Joy’ in the areas of lookup rules, the ‘build script’ and comprehensive ‘test file’. RIT is willing to add the missing copyright notice to these files;
and RIT asked Santhosh to consider:
- Preserve the copyright of the original authors of the ‘lookup rules’ and Naming convention (notation for Glyphs) in all these fonts. The copyright and license statement should read:
“Copyright: Digitized data copyright (c) 2004–2005 Rachana Akshara Vedi (Chitrajakumar R, Hussain KH, Gangadharan N, Vijayakumaran Nair, Subash Kuraiakose), (c) 2006–2016 Hussain KH, Suresh P, Santhosh Thottingal, Rajeesh K Nambiar, Swathanthra Malayalam Computing (http://smc.org.in). This file is licensed under OFL 1.1.”
- The Fontforge based ‘build script’ added by Santhosh used to generate TTF/OTF/WOFF/WOFF2 files is adapted from that of Amiri font by Khaled Hosny  without preserving copyright or attribution. RIT requests to credit the original author[s] of this tool. It is of our opinion that removing copyright statements from a free software program code is illegal and immoral. It is also hypocritical when a person who asserts one’s own credit does this crime to other well-known and respected free software developer[s].
- Test cases in the ‘test file’ are contributed by various contributors, RIT request to add the attribution of such contributors to the extent possible (Kavya Manohar, Santhosh Thottingal, Rajeesh KV). Santhosh has responded to this request as “test cases were mainly prepared by Kavya and no need to have attribution”, but RIT firmly believes the copyright statements of the contributors must be added.
- The original author of ‘mlym.sty’ file  to typeset Unicode Malayalam using XeTeX is Suresh P, which was enhanced by Rajeesh KV with inputs from Hussain KH. Due to frequent requests on how to typeset Malayalam using Unicode, in 2013 Rajeesh wrote a wiki page  with basic details, which was later extended by other developers with instructions to install and setup XeTeX packages. This wiki article was later extended by Santhosh by adding matter from Wikipedia. This article was then copied and published in Santhosh’s blog  without attributing the authors, and  is frequently provided by Santhosh as the first response to general public asking for documentation on how to typeset Malayalam using XeTeX. It is shockingly hypocritical that plagiarism is practised by a well known free software developer who asserts one’s own credit without any respect to others copyright or credit. RIT would like Santhosh to either: (a) redact  and redirect to  instead, or (b) credit the original authors in .
RIT stopped the analysis and investigation of Santhosh’s claim at this point, as we have identified the root cause of missing copyrights and these are the important topics directly affecting RIT developers.
RIT tried to resolve the issue in private discussion with Santhosh Thottingal but unfortunately it did not succeed. Santhosh has not agreed to reinstate the copyright statement of original authors. Santhosh did not respond to many of the pointed questions we raised and deflected on answering others. Santhosh also refused to clarify what he means by ‘credit’ despite repeated pointed questions. Santhosh withdrew his claim for credit in one of the emails; and it is possible that he could change the mind any time and the issue could resurface. This surrounds the fonts by SMC and RIT in Fear, Uncertainty and Doubt (which the corporate proprietary companies successfully used against free software for years) and put all the individual users and organizations and developers using these fonts under legal risk and moral ambiguity.
- RIT has added proper copyright statements to all the software used in building its fonts, viz. ‘Sundar’ and ‘ TN Joy’ [11,12].
- RIT believes that our primary responsibility is towards the individual and institutional users of our fonts and developers depending on our tools; and they should be able to use our fonts and tools without any legal risk or moral ambiguity. RIT, to the best of its knowledge, has fulfilled that responsibility and strive to do so.
- RIT also understands that as with any issue in the free software world, the community would be divided, and it is a painful thing. RIT request the community to carefully consider all the facts before making a choice.
This will be the final public statement of RIT on the copyright issue raised by Santhosh Thottingal.
