Comment 1 Henri Sivonen 2009-08-21 10:20:11 CEST

The original summary for this bug was longer than 255 characters, and so it was truncated when Bugzilla was upgraded. The original summary was:

Remove U+000B LINE TABULATION (VT) from the list of characters treated like a space character in HTML, for consistency with CSS. This is incompatible with IE7, but apparently IE has all kinds of complications here and in any case IE8 doesn't treat U+000B as a space character.
