<brief_description>
A fallback implementation of Godot's text server, without support for BiDi and complex text layout.
</brief_description>
<description>
A fallback implementation of Godot's text server. This fallback is faster than [TextServerAdvanced] for processing a lot of text, but it does not support BiDi and complex text layout.
[b]Note:[/b] This text server is not part of official Godot binaries. If you want to use it, compile the engine with the option [code]module_text_server_fb_enabled=yes[/code].
