Add Nata Sans font family

[dnlzqn]

This is a clean resubmission of Nata Sans, following feedback from the Google Fonts team.

• The previous pull request (Add Nata Sans font family by Daniel Uzquiano #9477) was closed after a force-push broke the commit history.
• This new submission includes:
  • Correct file structure (METADATA.pb, OFL.txt, and the font file at the top level)
  • article/ folder with ARTICLE_en_us.html and Nata.svg
  • A fully cleaned commit history, based on the latest repository standards

Thank you for your time and guidance — looking forward to your review.

Hi @m4rc1e @emmamarichal, just a quick note to let you know I opened this new PR after accidentally closing the previous one. Thanks again for your help and feedback!

[davelab6]

@dnlzqn thanks for posting this! Usually we prefer an issue than a PR, so that we can discuss your project there and get consensus to add it and what will be required, and then later once our requirements are met, then we prepare a PR ourselves that is sure to pass through our onboarding validation processes quickly. But its great you are trying to make a PR directly :) I did a review here in gh and spotted a few things in the text shown, I didn't look inside your TTF, but I'm sure @emmamarichal and @m4rc1e will do an excellent review soon :)

[emmamarichal]

Thank you @davelab6 :) I'll give you a review regarding outlines as soon as possible, thanks again for your submission!

[dnlzqn]

Thanks for the feedback and for the clarification about the usual process, @davelab6 — totally noted for future contributions!

I've now:
– Updated the copyright line in METADATA.pb
– Clarified wording in ARTICLE_en_us.html ("Latin including Vietnamese and Cyrillic")
– Updated the SVG (Nata.svg) accordingly

Let me know if there's anything else to address. Happy to adjust anything further to align with GF standards.

Hi @dnlzqn!

First of all, thanks again for that submission, the font covers a lot of langages, that's really appreciated.

Here you can find a first review:

Fontspector Fails and Warns you can easily fix

🔥 FAIL Check tabular widths don't have kerning. (tabular_kerning)
-> remove kerning on your tabular figures

⚠️ WARN Are there caret positions declared for every ligature? (ligature_carets)
-> add anchors to ligatures (cmd + U)

⚠️ WARN Check font contains no unreachable glyphs (unreachable_glyphs)
⚠️ WARN Glyph names are all valid? (valid_glyphnames)
-> Remove or mark as non-export all the .001 glyphs

⚠️ WARN Font has correct separator glyphs? (googlefonts/separator_glyphs)
-> add U+2028 and U+2029

Outlines / alignement / Design issues

Note: for each point, check it in each masters.

• 'W' looks too wide
• 'Q' tail is maybe a bit short
• 'ogonek' should be drawn a bit differently, you can check this: https://www.twardoch.com/download/polishhowto/ogonek.html
• Glyphs with bar or slash have to be corrected (see screenshots)
• 'ae': 'e' design should be the same as the actual 'e'
• descenders should have the same size in all masters (example with the 'p')

Other

• In OFL.txt, change https://scripts.sil.org/OFL to https://openfontlicense.org/

Hi @emmamarichal,

Thanks again for your detailed review — I’ve now implemented all the changes you requested:

• Removed kerning on tabular figures
• Added caret positions to all ligatures
• Added separator glyphs U+2028 and U+2029
• Removed or renamed .001 glyphs, cleaned up names
• Fixed OFL.txt URL and restored standard license body
• Corrected outlines across masters (W width, Q tail, ogonek, bars, ae, descenders…)
• Updated METADATA.pb subsets and structure (including menu, sorted alphabetically)

Let me know if anything else needs adjustment. Thanks again for your support!

Best,
Daniel
