Use HTML5 dir="auto" in text displaying widget to automatically support RTL languages

HTML5 has introduced a new possible value for the dir attribute of HTML elements namely auto to make it possible to change the text direction to right to left (RTL) automatically when the text content starts with characters from languages such such arabic, hebrew or farsi for instance.

Unfortunately this is not yet available as a CSS declaration hence the need to use an HTML attribute.

Note: this feature is currently supported by webkit based browsers. Firefox support is not yet implemented, see: https://bugzilla.mozilla.org/show_bug.cgi?id=548206
