JS example: 'hello_there'.replace(/[\w\-]+/, 'xxx') This should return the string "xxx" like in Safari 3.1.2 or Firefox 3.x. The current WebKit Build returns "xxx_there" because the character class shorthand \w seems not to include the underscore anymore. Removing the "\-" of the range fixes the bug. For some reasons you cannot simply place a underscore within a character class to fix the erratic behaviour related to the \w shorthand. The underscore must be escaped (this is normally not necessary). 107701 1 ap 2009-01-30 08:40:04 -0800 Giving this full regression treatment. On IRC, it was mentioned that the issue is still present in current nightlies (I haven't tried to reproduce it). 107706 2 27183 gianni 2009-01-30 09:08:14 -0800 Created attachment 27183 This is a test case for the bug which provides an example.
