• For each symbol, add its hex code (0xf641 for the 'Ad' icon, for example) to the Range list in the fonts.json file
• Convert this hex value into a UTF-8 code using this site
• Define the new symbols in src/displayapp/screens/Symbols.h:

static constexpr const char* newSymbol = "\xEF\x86\x85";

the config file format:

inside fonts, there is a dictionary of fonts, and for each font there is:

• sources - list of file,range(,symbols) wanted (as a dictionary of those)
• bpp - bits per pixel.
• size - size.
• patches - list of extra "patches" to run: a path to a .patch file. (may be relative)
• compress - optional. default disabled. add "compress": true to enable

Navigation font

navigtion.ttf is created with the web app icomoon by importing the svg files from src/displayapp/icons/navigation/unique and generating the font. lv_font_navi_80.json is a project file for the site, which you can import to add or remove icons.
