I want remove unnecessary symbols from font «SFUI Text Regular». File size 104kb.
Tried use FontForge. Deleted ~50% symbols. Save font. Tried use on the website. Result: the file size has decreased (104kb > 35kb), but the letters are thinner than originally. (i am sure, that this is wasn't system font, it's same font, but thinner)
Tried use fonttools, pyftsubset command.
pyftsubset font.woff --output-file=font2.woff --unicodes-file=symbols.txt
symbols.txt — list of needed symbols in format U+XXXX. Checked few times for truth.
Deleted ~50% symbols. Got needed font file. File size increased (104kb > 110kb). And this font give me originally thickness of letters, but i need decrease file size.
2.1. Converting
Tried convert woff to woff2 (convertio service). Decreased file size. Tried font file: thinner letters. Tried convert woff2 to woff back. Decreased file size. Result: thinner letters.
I tried few more programs and services for this.
FontCreator Pro helped decide problem. No specific settings. I just opened it, deleted characters, saved it.
