text

to modify.

	offset		the offset, in bytes, from the beginning of the string if >= 0, the offset from the end of the string if < 0. Note that this does not do UTF-8 validation, so you should only delete at UTF-8 sequence boundaries.
	length		the length of text to delete, in bytes, or -1 for the remainder of the string.

This function should be called on the thread that created the text.

This function is available since SDL_ttf 3.0.0.
