You don't actually say so, but you give me the impression that you think NBSP is a fixed-width space. It isn't; it can assume any width greater than zero, just as SPACE can; in particular, when used before a NSM, I would expect it to have the same width as the NSM. > I would like to repeat my earlier proposal for a new character ISOLATED > COMBINING MARK BASE.

Except for not being letters, SP and NBSP have, or ought to have, exactly this behavior. -- "Well, I'm back." --Sam John Cowan <[EMAIL PROTECTED]>
