Add new symbols:

• Browse the cheatsheet and find your new symbols
• For each symbol, add its hex code (0xf641 for the 'Ad' icon, for example) to the Range list (Remember to keep this readme updated with newest range list)
• 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";

Navigation font

To create the navigtion.ttf I use the web app icomoon this app can import the svg files from the folder src/displayapp/icons/navigation/unique and creat a ttf file the project for the site is lv_font_navi_80.json you can import it to add or remove icons

You can also use the online LVGL tool to create the .c

ttf file : navigation.ttf name : lv_font_navi_80 size : 80px Bpp : 2 bit-per-pixel range : 0xe900-0xe929

$lv_font_conv --font navigation.ttf -r '0xe900-0xe929' --size 80 --format lvgl --bpp 2 --no-prefilter -o lv_font_navi_80.c

I use the method above to create the other ttf
