Hi Bruce, Having gone back to the part of your note about missing characters, now I'm confused. Unicode 2.0 (1996), in Chapter 7 'Code Charts', on page 7-180 in 'Mathematical operators' defines: U+2285 NOT A SUPERSET OF (canonical decomposition) U+2283 (SUPERSET OF) + U+0338 (COMBINING LONG SOLIDUS OVERLAY U+22A2 RIGHT TACK (alternative name) proves, implies, yields These characters are *not* missing from Unicode/ISO-10646, although they may have missing character entity names in HTML.

Hi Al and Bruce, In Unicode 2.0 (1996), in Chapter 7 'Code Charts', on page 7-155 'General punctuation', the following character is defined: U+2011 NON-BREAKING HYPHEN (cross reference) U+002D - HYPHEN-MINUS I believe this is what you're looking for. I've copied Martin Duerst (W3C Internationalization leader) to verify.

There is the whitespace=nowrap formatting property that in theory should accomplish what you are after if you wrap the whole <span class='my-nowrap'>hyphenated-expression</span> and then style this class or ID with the property whitespace=nowrap. 2. Missing characters should go to the Unicode Consortium. It would be good to get in touch with the internationalization, XML InfoSet, and/or math groups depending on just what the character is, to find out if there are others in W3C that care about this character one way or another.
