I ran into a case where all v's were removed from my text. I went trough all the scripts and found that one was doing a .replace(/[\t\v\u00a0\u2028\u2029]+/g, ' '). Because Safari RegExp apparently doesn't know the \v (vertical tab), it instead opted to replace all my v's

testcase of vertical tab matching
This test case, shows that when replacing vertical tab \v, matches normal v.
Seems fixed in a nightly build. Original report was with Safari 3.0.2
