Twenty Twenty-Three: problem with some international characters

[cvorko]

Theme Twenty Twenty-Three has default font DM Sans. When using this font, there are no characters for Croatian characters (čćžšđČĆŽŠĐ) and a replacement font is used.

In the attached image there is a sample WordPress text (showed when editing styles), and Croatian characters are marked - they are obviously in another font.

I can change the font, but beginners (at least in the first few days) use default theme and default font.

Text with some Croatian characters - not in default DM Sans font.

Thanks for the report!

Twenty Twenty-Two's DM Sans files seem to include the Latin Extended characters, but Twenty Twenty-Three falls back to the browser's default sans-serif for those.

Uses WOFF2 files from the ​Google Fonts repository and adds font credits from Twenty Twenty-Two.

Latin Extended characters in DM Sans with PR 5123

[sabernhardt]

The WOFF2 files from the Google Fonts repo include almost all of ​Latin Extended set A plus nine characters of set B. (I switched my default font to Comic Sans to make the missing characters from set A stand out more.) All ten of the Croatian examples would be supported with those files.

I also checked the theme's other three bundled fonts, and each already supports more characters in Extended-A than DM Sans. IBM Plex Mono only lacks ſ, Inter supports all but ʼn and ſ, and Source Serif Pro also has additional characters but does not have six of the glyphs found in the full DM Sans (Ĭ ĭ IJ ij Ǽ ǽ).

Note: I did not have success applying the patch with SVN due to the binary font files. Also, the readme change is proposed separately in #59483.

This ticket was discussed during the 6.4 bug scrub today. We dropped it in #core-test to hopefully get some testers on it.

[nicolefurlan]

Just checking on this ticket as we're just over a week from 6.4 RC1. @cvorko would you be willing to test the patch to see if your reported issue is resolved?

WOFF2 files (with license)

[sabernhardt]

If the patch needs to be regenerated for binary files, I uploaded the four WOFF2 files with names to fit Twenty Twenty-Three.

For testing the extended characters, you could copy and paste (in Code view) the ​blocks I made.

I was also not able to apply the patch, but needed to manually replace the existing font files with the provided files.

@dingo_d has helped test the replacement fonts in Croatian and confirms they are working.
