Make a Windows-1252 Variable Font Subset With Only R/I/B/BI Styles
Let’s assume you have a variable font with Latin, Greek, and Cyrillic letters, upright and italic styles and a large weight range.
You can use the subsetting function of Corretto to additionally produce a variable font only containing the Windows-1252 (Latin) character set, and a weight range from Regular to Bold, including italics.
In the YAML file, we first define an entry under the charsets key with the unique ID win-1252 and a list of Unicode values in hexadecimal notation:
charsets:
- id: win-1252
unicodes:

Then, under the ranges key, we define how the variation axes will be modified.
-
ital: The italic axis is kept as is. You could also omit this entry. -
wght: The original range of the weight axis is 200 to 700, with Regular at 400 being the default master. We limit the weight axis range to 400 – 700 (Regular to Bold). The default master stays the same. -
YTDE: The descender depth axis is removed from the font, because there are nominandmaxvalues given. It will be fixed at its former default value, -188.
ranges:
- id: ribbi
axes:
- tag: ital
- tag: wght
min: 400
def: 400
max: 700
- tag: YTDE
def: -188.0
And finally, under the subsets key, we bring everything together in an entry referencing our range ID and charset ID. The family name is replaced with a new name, “Sudo Basic”. The modified fonts will be saved in the directory “Subset-Basic”. The directory will be created if necessary. The out_dir directory path is relative to the export destination.
subsets:
- range: ribbi
charset: win-1252
family:
replace: Sudo Basic
out_dir: Subset-Basic
