Add Charis SIL #3757

jvgaultney · 2021-08-25T17:00:07Z

Charis SIL (github) has never been on GF even though it is a widely used OFL font family popular in academic circles.

Charis SIL is loosely based on Charter but does have significant differences (esp. in the serifs). The GF catalog already lists two versions of Charter (Charter BT and ITC Charter), however nothing that is natively hosted on GF. Charis SIL also has a much broader character set including the same full extended Latin/Cyrillic support as Gentium and Andika.

Proposal:

Add Charis SIL to GF

I'd love to see it as well. @jvgaultney can you suggest which version would be best? Is there still Compact vs. non-compact?

Proposal sounds good

Oh, this would be fantastic to see included!

You never got a response to your question, @twardoch, but yes there are options with Charis SIL. A notorious issue with this font is that its line spacing is extremely wide compared to Charter and Georgia or other similar fonts. The FAQ calls for adjusting your line height at the per-application level to compensate for this.

However, that is contentious guidance since many applications don't support line heigh adjustment. And it makes the font a poor choice for embedding (e.g. ebooks), since you would be forcing unsophisticated end users to make adjustments. So the SIL group offers the ability to download a version with "compact" (i.e. typical) line spacing, by:

Going to their TypeTuner web page.
Selecting Charis, and then adjusting the the "Line spacing" option at the bottom to "tight" (leaving the defaults for all other settings).
Entering a suffix (e.g. "compact") that will be appended to the font filenames.

You can see the difference in line spacing between the raw vs. tuned versions of the font:

The Fedora Linux project distributes both a raw and a compact version of the font. However, if only one version is to be included in the Google Fonts archive, then I advocate for the compact version. Because this is far more in line with most common fonts in terms of line spacing, and therefore won't cause users as much surprise and aggravation.

jvgaultney · 2022-02-16T14:52:49Z

Charis SIL has been updated to v6.101, which supports TypeTuner Web as Steve mentioned. We recommend that the normal (wide line spacing) version be hosted on Google as it is the primary version we maintain. It also meets the Google vertical metrics guidelines. The 'Compact' version is available through TypeTuner Web, but we no longer produce it as a separate package.
