Fontbakery reportFontbakery version: 0.8.2 [10] Changa[wght].ttf🔥 FAIL: Check `Google Fonts Latin Core` glyph coverage.--- Rationale --- Google Fonts expects that fonts in its collection support at least the minimal set of characters defined in the `GF-latin-core` glyph-set.
🔥 FAIL: METADATA.pb: Designers are listed correctly on the Google Fonts catalog?--- Rationale --- Google Fonts has a catalog of designers. This check ensures that the online entries of the catalog can be found based on the designer names listed on the METADATA.pb file. It also validates the URLs and file formats are all correctly set.
⚠ WARN: Check copyright namerecords match license file.--- Rationale --- A known licensing description must be provided in the NameID 14 (LICENSE DESCRIPTION) entries of the name table. The source of truth for this check (to determine which license is in use) is a file placed side-by-side to your font project including the licensing terms. Depending on the chosen license, one of the following string snippets is expected to be found on the NameID 13 (LICENSE DESCRIPTION) entries of the name table: - "This Font Software is licensed under the SIL Open Font License, Version 1.1. This license is available with a FAQ at: https://scripts.sil.org/OFL" - "Licensed under the Apache License, Version 2.0" - "Licensed under the Ubuntu Font Licence 1.0." Currently accepted licenses are Apache or Open Font License. For a small set of legacy families the Ubuntu Font License may be acceptable as well. When in doubt, please choose OFL for new font projects.
⚠ WARN: License URL matches License text on name table?--- Rationale --- A known license URL must be provided in the NameID 14 (LICENSE INFO URL) entry of the name table. The source of truth for this check is the licensing text found on the NameID 13 entry (LICENSE DESCRIPTION). The string snippets used for detecting licensing terms are: - "This Font Software is licensed under the SIL Open Font License, Version 1.1. This license is available with a FAQ at: https://scripts.sil.org/OFL" - "Licensed under the Apache License, Version 2.0" - "Licensed under the Ubuntu Font Licence 1.0." Currently accepted licenses are Apache or Open Font License. For a small set of legacy families the Ubuntu Font License may be acceptable as well. When in doubt, please choose OFL for new font projects.
⚠ WARN: Are there caret positions declared for every ligature?--- Rationale --- All ligatures in a font must have corresponding caret (text cursor) positions defined in the GDEF table, otherwhise, users may experience issues with caret rendering. If using GlyphsApp or UFOs, ligature carets can be defined as anchors with names starting with 'caret_'. These can be compiled with fontmake as of version v2.4.0.
⚠ WARN: Is there kerning info for non-ligated sequences?--- Rationale --- Fonts with ligatures should have kerning on the corresponding non-ligated sequences for text where ligatures aren't used (eg https://github.com/impallari/Raleway/issues/14).
⚠ WARN: A static fonts directory with at least two fonts must accompany variable fonts--- Rationale --- Variable font family directories kept in the google/fonts git repo may include a static/ subdir containing static fonts. These files are meant to be served for users that still lack support for variable fonts in their web browsers.
⚠ WARN: Ensure fonts have ScriptLangTags declared on the 'meta' table.--- Rationale --- The OpenType 'meta' table originated at Apple. Microsoft added it to OT with just two DataMap records: - dlng: comma-separated ScriptLangTags that indicate which scripts, or languages and scripts, with possible variants, the font is designed for - slng: comma-separated ScriptLangTags that indicate which scripts, or languages and scripts, with possible variants, the font supports The slng structure is intended to describe which languages and scripts the font overall supports. For example, a Traditional Chinese font that also contains Latin characters, can indicate Hant,Latn, showing that it supports Hant, the Traditional Chinese variant of the Hani script, and it also supports the Latn script The dlng structure is far more interesting. A font may contain various glyphs, but only a particular subset of the glyphs may be truly "leading" in the design, while other glyphs may have been included for technical reasons. Such a Traditional Chinese font could only list Hant there, showing that it’s designed for Traditional Chinese, but the font would omit Latn, because the developers don’t think the font is really recommended for purely Latin-script use. The tags used in the structures can comprise just script, or also language and script. For example, if a font has Bulgarian Cyrillic alternates in the locl feature for the cyrl BGR OT languagesystem, it could also indicate in dlng explicitly that it supports bul-Cyrl. (Note that the scripts and languages in meta use the ISO language and script codes, not the OpenType ones). This check ensures that the font has the meta table containing the slng and dlng structures. All families in the Google Fonts collection should contain the 'meta' table. Windows 10 already uses it when deciding on which fonts to fall back to. The Google Fonts API and also other environments could use the data for smarter filtering. Most importantly, those entries should be added to the Noto fonts. In the font making process, some environments store this data in external files already. But the meta table provides a convenient way to store this inside the font file, so some tools may add the data, and unrelated tools may read this data. This makes the solution much more portable and universal.
⚠ WARN: Glyph names are all valid?--- Rationale --- Microsoft's recommendations for OpenType Fonts states the following: 'NOTE: The PostScript glyph name must be no longer than 31 characters, include only uppercase or lowercase English letters, European digits, the period or the underscore, i.e. from the set [A-Za-z0-9_.] and should start with a letter, except the special glyph name ".notdef" which starts with a period.' https://docs.microsoft.com/en-us/typography/opentype/spec/recom#post-table In practice, though, particularly in modern environments, glyph names can be as long as 63 characters. According to the "Adobe Glyph List Specification" available at: https://github.com/adobe-type-tools/agl-specification
⚠ WARN: Does the font have a DSIG table?--- Rationale --- Microsoft Office 2013 and below products expect fonts to have a digital signature declared in a DSIG table in order to implement OpenType features. The EOL date for Microsoft Office 2013 products is 4/11/2023. This issue does not impact Microsoft Office 2016 and above products. As we approach the EOL date, it is now considered better to completely remove the table. But if you still want your font to support OpenType features on Office 2013, then you may find it handy to add a fake signature on a dummy DSIG table by running one of the helper scripts provided at https://github.com/googlefonts/gftools Reference: https://github.com/googlefonts/fontbakery/issues/1845
