Special Characters in InkHUD

Because of hardware constraints, fonts contain a limited number of characters. By default, InkHUD is built with a "Western European" character set (Windows-1252). Fonts are also provided for "Central European" and "Cyrillic" character sets.

Choosing a Character Set

Wikipedia maintains a comprehensive list of which languages are supported by each character set.

• https://en.wikipedia.org/wiki/Windows-1252 - Western European (InkHUD default)
• https://en.wikipedia.org/wiki/Windows-1250 - Central European
• https://en.wikipedia.org/wiki/Windows-1251 - Cyrillic

Changing the Character Set

To use an alternative character set, you will need to build the Meshtastic firmware.

The choice of font is set in /variants/<Device Model>/nicheGraphics.h.

Find the lines:

// Prepare fonts
InkHUD::Applet::fontLarge = FREESANS_9PT_WIN1252;
InkHUD::Applet::fontSmall = FREESANS_6PT_WIN1252;

Replace with either:

InkHUD::Applet::fontLarge = FREESANS_9PT_WIN1250;
InkHUD::Applet::fontSmall = FREESANS_6PT_WIN1250;

InkHUD::Applet::fontLarge = FREESANS_9PT_WIN1251;
InkHUD::Applet::fontSmall = FREESANS_6PT_WIN1251;
