Subject: Fix ICU search problem / caret not escaped.
X-Git-Tag: v2.0.37~13^2~1

Fix ICU search problem / caret not escaped.

For some ICU versions (4.0.1, possibly others) the normalized term
may include a caret (^) in it and so this chracter must also be
escaped before turned into a regular expression.
