That is incorrect. It is certainly possible to use 'ex' for width.
the quote URL says:

Whether you'll get consistent results in browser is a different
matter. On Windows, the ex unit is really broken in Safari 4b+/Chrome,
well implemented in IE 8 (Vista and Win 7 only) and Gecko browsers.
Opera always treated it as 1/2 em. On Mac, it is half-broken in Safari
4b+; it works fine in Gecko based browsers.
As for the original question, as asked, that cannot be done in CSS –
yet. Some kind of text-justify value would do, but atm not implemented
in any browser.
This maybe (future !):
<http://www.w3.org/TR/css3-text/#text-justify>
maybe some javascript trick might do.
