Add utf8_fprintf helper that returns correct number of columns
Since command usages can be translated, they may include utf-8 encoded strings, and the output in console may not align well any more. This is because strlen() is different from strwidth() on utf-8 strings. A wrapper utf8_fprintf() can help to return the correct number of columns required.
