At least they appear in the new-messages page

My guess is that the problem comes from " being the delimiter of the address of the hyperlink.
So the browser does not know whether the " is to be displayed or to be interpreted as the end of the address (and ignore all the rest till the > character).

As single quotes (') are not defined as delimiters for the address (single quotes are no special html characters at all, so they should not make any trouble), they don't interfere with the interpretation of the string in the browser

Just to distinguish between quotes and apostrophe, it would be better to replace double quotes (") by two single quotes (''), e.g. LyrReq: ''I don't know''
