Issue with displaying special characters on EINK display using writeIn command

[IDK1854]

I am encountering difficulties while trying to display special characters (such as ěščřé and ČŘÉ) on the EINK display using the writeIn command. Despite having generated a custom font that includes these characters, only a few of them are actually displayed, while the other half of the letters seems to be skipped.

Upon inspecting the font file, I can confirm that the special characters are present.

Library version: 0.3.0
Arduino version: 1.8.16

custom font: custom_font.h.txt
code: code_ttgo.txt

Thanks :)
