Additional fonts for D2GL's HD Text mode.
Fontin font best known from Path of Exile was converted using sdf atlas type. Otherwise there are too many glyph errors. Due to that there are some limitation - you might turn off overshadow for drop items, otherwise it looks weird.
Antiqua SSK was font used by Sacred 2.
Check official D2GL documentation here
TL;DR version. Copy data into Diablo II base directory, edit data/assets/atlases/default.txt depending on what font you want to use, then launch game with -direct.
I only provided unchanged default.txt, here is entry that was used for taking screenshot as an example:
14 | AntqSSK | 12.000 | 1.040 | 0.050 | 1.100 | 0.500 | 0.070 | -0.200 | 0.050
