<brief_description>
Font class is set of font data sources used to draw text.
Base class for fonts and font variations.
</brief_description>
<description>
Font contains a set of glyphs to represent Unicode characters, as well as the ability to draw it with variable width, ascent, descent and kerning.
[b]Note:[/b] A character is a symbol that represents an item (letter, digit etc.) in an abstract way.
[b]Note:[/b] A glyph is a bitmap or shape used to draw a one or more characters in a context-dependent manner. Glyph indices are bound to the specific font data source.
[b]Note:[/b] If a non of the font data sources contain glyphs for a character used in a string, the character in question will be replaced with a box displaying its hexadecimal code.
[codeblocks]
[gdscript]
var font = Font.new()
font.add_data(load("res://BarlowCondensed-Bold.ttf"))
$"Label".set("custom_fonts/font", font)
$"Label".set("custom_fonts/font_size", 64)
[/gdscript]
[csharp]
var font = new Font();
font.AddData(ResourceLoader.Load&lt;FontData&gt;("res://BarlowCondensed-Bold.ttf"));
GetNode("Label").Set("custom_fonts/font", font);
GetNode("Label").Set("custom_font_sizes/font_size", 64);
[/csharp]
[/codeblocks]
To control font substitution priority use [FontData] language and script support.
Use language overrides to use same [Font] stack for multiple languages:
[codeblocks]
[gdscript]
# Use Naskh font for Persian and Nastaʼlīq font for Urdu text.
var font_data_fa = load("res://NotoNaskhArabicUI_Regular.ttf");
font_data_fa.set_language_support_override("fa", true);
font_data_fa.set_language_support_override("ur", false);
var font_data_ur = load("res://NotoNastaliqUrdu_Regular.ttf");
font_data_ur.set_language_support_override("fa", false);
font_data_ur.set_language_support_override("ur", true);
[/gdscript]
[csharp]
// Use Naskh font for Persian and Nastaʼlīq font for Urdu text.
var fontDataFA = ResourceLoader.Load&lt;FontData&gt;("res://NotoNaskhArabicUI_Regular.ttf");
fontDataFA.SetLanguageSupportOverride("fa", true);
fontDataFA.SetLanguageSupportOverride("ur", false);
var fontDataUR = ResourceLoader.Load&lt;FontData&gt;("res://NotoNastaliqUrdu_Regular.ttf");
fontDataUR.SetLanguageSupportOverride("fa", false);
fontDataUR.SetLanguageSupportOverride("ur", true);
[/csharp]
[/codeblocks]
Use script overrides to specify supported scripts for bitmap font or for less common scripts not directly supported by TrueType format:
[codeblocks]
[gdscript]
# Use specified font for Egyptian hieroglyphs.
var font_data = load("res://unifont.ttf");
font_data.set_script_support_override("Egyp", true);
[/gdscript]
[csharp]
// Use specified font for Egyptian hieroglyphs.
var fontData = ResourceLoader.Load&lt;FontData&gt;("res://unifont.ttf");
fontData.SetScriptSupportOverride("Egyp", true);
[/csharp]
[/codeblocks]
Font is the abstract base class for font, so it shouldn't be used directly. Other types of fonts inherit from it.
