 		Font contains a Unicode-compatible character set, as well as the ability to draw it with variable width, ascent, descent and kerning. For creating fonts from TTF files (or other font formats), see the editor support for fonts.

If this replacement character isn't available in the DynamicFont, the character will be hidden without displaying any replacement character in the string.

 		Label displays plain text on the screen. It gives you control over the horizontal and vertical alignment and can wrap the text inside the node's bounding rectangle. It doesn't support bold, italics, or other formatting. For that, use [RichTextLabel] instead.
 		[b]Note:[/b] Contrarily to most other [Control]s, Label's [member Control.mouse_filter] defaults to [constant Control.MOUSE_FILTER_IGNORE] (i.e. it doesn't react to mouse input events). This implies that a label won't display any configured [member Control.hint_tooltip], unless you change its mouse filter.

 		[b]Note:[/b] Assignments to [member bbcode_text] clear the tag stack and reconstruct it from the property's contents. Any edits made to [member bbcode_text] will erase previous edits made from other manual sources such as [method append_bbcode] and the [code]push_*[/code] / [method pop] methods.
 		[b]Note:[/b] RichTextLabel doesn't support entangled BBCode tags. For example, instead of using [code][b]bold[i]bold italic[/b]italic[/i][/code], use [code][b]bold[i]bold italic[/i][/b][i]italic[/i][/code].
 		[b]Note:[/b] Unlike [Label], RichTextLabel doesn't have a [i]property[/i] to horizontally align text to the center. Instead, enable [member bbcode_enabled] and surround the text in a [code][center][/code] tag as follows: [code][center]Example[/center][/code]. There is currently no built-in way to vertically align text either, but this can be emulated by relying on anchors/containers and the [member fit_content_height] property.
