@ -31,6 +31,23 @@ Add new symbols:
static constexpr const char* newSymbol = "\xEF\x86\x85";
```
#### Fix the zero symbol
If you don't wish the inner dot of the 0 (zero) symbol to stick to the boundary), edit `src/displayapp/fonts/jetbrains_mono_bold_20.c` and replace:
/* U+0030 "0" */
0x3f, 0x1f, 0xef, 0x3f, 0x87, 0xe1, 0xf8, 0x7f,
0xdf, 0xf7, 0xe1, 0xf8, 0x7e, 0x1f, 0xcf, 0x7f,
0x8f, 0xc0,
with
/* U+0030 "0" */
0x3f, 0x1f, 0xef, 0x3f, 0x87, 0xe1, 0xf8, 0x7e,
0xdf, 0xb7, 0xe1, 0xf8, 0x7e, 0x1f, 0xcf, 0x7f,
0x8f, 0xc0,
(there are two changes: 7f -> 7e and f7 -> b7)
## Simple method to generate a font
If you want to generate a basic font containing only numbers and letters, you can use the above settings but instead of specifying a range, simply list the characters you need in the Symbols field and leave the range blank. This is the approach used for the PineTimeStyle watchface.
