Description Anuja 2007-04-18 11:38:25 UTC

Hyphenate does not work correctly when the data in the block has numeric 
characters or commas...

In the example below, only the data in the first table-row gets hyphenated 
correctly

I think I see the problem here, but I'm not sure it's a bug... Not all of it, that is.
Hyphenation is, in fact, only applicable to pure alphabetical characters. Strictly speaking, one cannot 
'hyphenate' a seven-digit number, if I interpret correctly.

That said, the case with the comma maybe could be handled better. Currently, from the point on where 
the hyphenator meets the comma (or more generally: any non-letter), it does not even attempt to 
hyphenate anymore.

What you're really looking for is unconditional wrapping of the text, rather than hyphenation, it seems. 
That would be wrap-option="wrap" on the blocks, which we claim to support according to the compliance 
page. After having a quick try, this feature seems to be broken, however...
