Fontbakery reportFontbakery version: 0.8.0 [1] Family checks⚠ WARN: Is the command `ftxvalidator` (Apple Font Tool Suite) available?--- Rationale --- There's no reasonable (and legal) way to run the command `ftxvalidator` of the Apple Font Tool Suite on a non-macOS machine. I.e. on GNU+Linux or Windows etc. If Font Bakery is not running on an OSX machine, the machine running Font Bakery could access `ftxvalidator` on OSX, e.g. via ssh or a remote procedure call (rpc). There's an ssh example implementation at: https://github.com/googlefonts/fontbakery/blob/main/prebuilt/workarounds /ftxvalidator/ssh-implementation/ftxvalidator
[12] JosefinSans-Italic[wght].ttf🔥 FAIL: Name table strings must not contain the string 'Reserved Font Name'.--- Rationale --- Some designers adopt the "Reserved Font Name" clause of the OFL license. This means that the original author reserves the rights to the family name and other people can only distribute modified versions using a different family name. Google Fonts published updates to the fonts in the collection in order to fix issues and/or implement further improvements to the fonts. It is important to keep the family name so that users of the webfonts can benefit from the updates. Since it would forbid such usage scenario, all families in the GFonts collection are required to not adopt the RFN clause. This check ensures "Reserved Font Name" is not mentioned in the name table.
🔥 FAIL: Ensure METADATA.pb does not use escaped strings.--- Rationale --- In some cases we've seen designer names and other fields with escaped strings in METADATA files. Nowadays the strings can be full unicode strings and do not need escaping.
🔥 FAIL: METADATA.pb: Designer is listed with the correct name on the Google Fonts catalog of designers?
⚠ WARN: Checking OS/2 achVendID.--- Rationale --- Microsoft keeps a list of font vendors and their respective contact info. This list is updated regularly and is indexed by a 4-char "Vendor ID" which is stored in the achVendID field of the OS/2 table. Registering your ID is not mandatory, but it is a good practice since some applications may display the type designer / type foundry contact info on some dialog and also because that info will be visible on Microsoft's website: https://docs.microsoft.com/en-us/typography/vendors/ This check verifies whether or not a given font's vendor ID is registered in that list or if it has some of the default values used by the most common font editors. Each new FontBakery release includes a cached copy of that list of vendor IDs. If you registered recently, you're safe to ignore warnings emitted by this check, since your ID will soon be included in one of our upcoming releases.

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.

⚠ 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: On a family update, the DESCRIPTION.en_us.html file should ideally also be updated.--- Rationale --- We want to ensure that any significant changes to the font family are properly mentioned in the DESCRIPTION file. In general, it means that the contents of the DESCRIPTION.en_us.html file will typically change if when font files are updated. Please treat this check as a reminder to do so whenever appropriate!
⚠ 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: Font contains '.notdef' as its first glyph?--- Rationale --- The OpenType specification v1.8.2 recommends that the first glyph is the '.notdef' glyph without a codepoint assigned and with a drawing. https://docs.microsoft.com/en-us/typography/opentype/spec /recom#glyph-0-the-notdef-glyph Pre-v1.8, it was recommended that fonts should also contain 'space', 'CR' and '.null' glyphs. This might have been relevant for MacOS 9 applications.

There's nothing wrong with the original line. Please run gftools add-font on this family again.
There was a problem hiding this comment.
Fontbakery lists a FAIL when the escape character is used (fonttools/fontbakery#2932). So this change removes the conflict of " and ' so that escape characters aren't necessary anymore.

⚠ 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

⚠ 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
