## Using in gint
**Disclaimer**: this is being worked on, but not implemented in gint yet.
When converting the font with `fxconv`, pass the name of a folder containing
block images instead of a simple image and set `charset` to `unicode`.
To convert the font with `fxconv`, pass the name of a folder containing
block images instead of a simple image and set `charset` to `unicode`. Note
that in this setting, `area` is ignored and the same grid parameters are
applied to all block images.
```sh
% fxconv -f uf5x7/ name:uf5x7 charset:unicode grid.size:5x7
```
When using the font, just call `dtext()` as usual and make sure the string is
encoded as utf8. The `u8` prefix can be used if your source file is not
encoded as utf8.
When using the fxSDK, you can simply create a folder under `assets-fx` or
`assets-cg` with the block files of your choice, for instance
`assets-fx/uf5x7/U+0020.png`.
To use the font, configure it with `dfont()`, then call `dtext()` as usual.
Make sure the string is encoded as UTF-8. The `u8` prefix can be used if your
source file is not encoded as UTF-8.
```c
dtext(5, 5, "Mézalors Δ=2 ⇒ ∀x∈S, x⊆Δ", BLACK, WHITE);
