CharFXTransformCharacter Property

The Unicode codepoint the character will use. This only affects non-whitespace characters. @GDScript.ord can be useful here. For example, the following will replace all characters with asterisks:

# `char_fx` is the CharFXTransform parameter from `_process_custom_fx()`.
# See the RichTextEffect documentation for details.
char_fx.character = ord("*")
