			<description>
				Adds a character to the font, where [code]character[/code] is the unicode value, [code]texture[/code] is the texture index, [code]rect[/code] is the region in the texture (in pixels!), [code]align[/code] is the (optional) alignment for the character and [code]advance[/code] is the (optional) advance.
