## Fonts
|
||||
|
||||
A recent addition to Bangle.js is the ability to use extra fonts with support for more characters.
|
||||
For example [all regions](https://banglejs.com/apps/?id=fontall) or [extended](https://banglejs.com/apps/?id=fontext) fonts.
|
||||
|
||||
Once installed, these apps cause a new font, `Intl` to be added to `Graphics`, which can be used with just `g.setFont("Intl")`.
|
||||
|
||||
There is also a `font` library - this is not implemented yet, but more information about the planned implementation
|
||||
is available at https://github.com/espruino/BangleApps/issues/3109
|
||||
|
||||
For now, to make your app work with the international font, you can check if `Graphics.prototype.setFontIntl` exists,
|
||||
and if so you can change the font you plan on using:
|
||||
|
||||
```JS
|
||||
myFont = "6x8:2";
|
||||
if (Graphics.prototype.setFontIntl)
|
||||
myFont = "Intl";
|
||||
```
|
||||
|
||||
Any new Font library must contain the metadata `"icon": "app.png", "tags": "font", "type": "module", "provides_modules" : ["fonts"],`
|
||||
and should provide a `font` library, as well as a `boot.js` that adds `Graphics.prototype.setFontIntl`. If you plan on
|
||||
making a new library it's best to just copy one of the existing ones for now.

# Fonts (all languages)
|
||||
|
||||
This library provides an international font that can be used to display messages.
|
||||
|
||||
The font is the 16px high [GNU Unifont](https://unifoundry.com/unifont/index.html).
|
||||
All characters from Unicode codepoint 32 up until codepoint 65535 (U+FFFF) are included here,
|
||||
which should be enough for most languages.
|
||||
|
||||
**The font is 2MB and takes a while to upload** - if you don't require all the languages
|
||||
it provides, consider installing another Font library like [extended fonts](https://banglejs.com/apps/?id=fontsext)
|
||||
that contains just the characters you need instead.
|
||||
|
||||
## Usage

# Fonts (extended)
|
||||
|
||||
This library provides an international font that can be used to display messages.
|
||||
|
||||
The font is the 16px high [GNU Unifont](https://unifoundry.com/unifont/index.html).
|
||||
All characters from Unicode codepoint 32 up until codepoint 1103 (U+044F) are included here,
|
||||
which should be enough for [around 90% of languages](https://arxiv.org/pdf/1801.07779.pdf#page=5)
|
||||
but **not** Chinese/Japanese/Korean.
|
||||
|
||||
The font is 20kb so is far more sensible than the [2MB all regions](https://banglejs.com/apps/?id=fontsall) font
|
||||
if you don't require non-latin languages.

|

|

Under `Settings -> Apps -> iOS Integration` there is
|

a `Time Sync` setting. This will enable syncing between the

|

Under `Settings -> Apps -> iOS Integration` there are some settings:
|
||||
|
||||
* `Time Sync` - This will enable syncing between the watch and iOS.
|
||||
* `Disable UTF8` - As of version 0.17 of this app, text strings from iOS
|
||||
are treated as UTF8. If you install a font library like https://banglejs.com/apps/?id=fontsall
|
||||
then the messages app will be able to use that to render characters from iOS. Without fonts
|
||||
installed, non-european (ISO8859-1) characters won't be displayed. If `Disable UTF8`
|
||||
is true *or no fonts library is installed*, text from iOS is converted to ISO8859-1, and known characters with equivalents
|
||||
within that range are converted (so text will display without a font library).
