Rather than use a template, you can use the combining diacritical mark U+0305 (combining overline). Example: x̅. The overline will be the same colour as the surrounding text. Needless to say, this is useful only for single letters (or very short strings), and appropriate only when the overline is semantically significant (as opposed to purely decorative). —Psychonaut18:54, 12 November 2007 (UTC)[reply]
