makefont stuck on step 2 for cjk

[tizxv22]

Hi, I'm trying to convert a font with cjk characters from ttf to fnt using makefont. (I combined NotoSans for cjk, arabic, and latin alphabet, it's about 583kb.)

The program works perfectly for another font I have (ProFont, about 56kb as a ttf, 27kb as fnt), but it's been stuck on step two for the past half hour, while it took a second to convert the other font. Is this normal?

I tried using https://ttf2fnt.com/, although it said file converted successfully, the output seems invalid, it is only 2kb and breaks my wps.

Not sure what is makefont. Did you try rockbox suggested tool?
From https://www.rockbox.org/wiki/RockboxExtras:

To convert your own TTF fonts to Rockbox's font format, you can use the convttf command line utility found in the Git source tree. Windows binaries can be downloaded from here (32 bit) or here (64 bit).

Based on this output you are running something pretty ancient.   Please use something more updated (eg the links that bahus provided) and see what happens.

I have a convttf tutorial here, covers building it as well. Hopefully this helps
