"""
|
||||
Hotfix a set of 'upstream' Noto CJK fonts to comply with fonts.google.com
|
||||
requirements. The following hotfixes are made:
|
||||
|
||||
* Reconstruct fvar/STAT tables to remove any weights which do not
|
||||
comply to the fonts.google.com expectations.
|
||||
* Rewrite the license description within the fonts to be the standard OFL
|
||||
text used in other fonts.
|
||||
* Replace the copyright sign © in the name table with ASCII '(c)'.
|
||||
* Rename the variable fonts using the GF Family[axes].ttf format.
|
||||
* Run various other source fixes using gftools.fix.
|
||||
* Restore the correct hhea ascent = 1160.
