I'd like to share with you the "State of Text Rendering 2024", a survey of the Free & Open Source fonts & text rendering landscape advancements since 2009.

FontTools 4.52.x is out with lots of interesting CFF goodies:
- Partial and static instancing of CFF2 variable fonts.
- Two new modules and command-lines: cffLib.CFFToCFF2 and cffLib.CFF2ToCFF for conversions between CFF and CFF2.
Check it out:

New @fonttools 4.45.0 is a `pip install --upgrade fonttools` away from you!
It contains my work on generating PDF/HTML from the `varLib.interpolatable` tool.
Check out the sample output:

Which Python version are you using FontTools with?
Context: we are thinking of dropping support for Python 3.7 before its scheduled end-of-life around mid next year: github.com/fonttools/fonttoo…
Shout if you'd like us to continue supporting Python 3.7 for a few more months!

33 votes • Final resultsFontTools 4.38.0 is out! Thanks to @behdad, the instancer can now change a variable font's axis default value, e.g. you have 2 masters Thin+Black and want a Regular in between, or wish to restrict min/max to a range that doesn't include the old default

f = TTFont(path/to/font.ttf)
for table in f["cmap"].tables:
# chr(97) == "a"
table.cmap[97] = "s"
AFAIK you have to set a glyph for a unicode and not a unicode for a glyph.

The power of @FontTools Pens is all about protocol: it's a standardized collection of methods with standardized call signatures. Any object that implements the pen protocol can be used by any code that writes to pens. Any code that writes to pens can be used with any pen.
This morning I've been subclassing a @FontTools BasePen, and it's such a cool abstraction. Easy to use, clean code, very expressive. Thanks @justvanrossum

The latest @FontTools release has a nice feature courtesy of some work @KhaledGhetas was doing for us: now subset OTL table contents by language system tags.

In case anyone out there wants to change the colors in my Megabase OpenType-SVG color fonts, here’s a quick demo where I dig into the guts of the font file with @FontTools TTX and mess with the color values. 🎨🎥🍿youtube.com/watch?v=_mywly0l…
