Regular expression search does not work for Japanese characters in Xbench 2.9

I’m using Xbench 2.9. I’m getting errors when I search these patterns in target with Regular Expression mode:

コメディ[^ー]|コメディ$
コラボ[^レ]

It seems specific characters such as and have something to do with this problem.

Xbench 2.9 is not Unicode and does not support DBCS characters in a set of a regular expression.

For Unicode support in regular expressions, you need to upgrade to Xbench 3.0.

Xbench 3.0 has a 30-day free trial (30 days of actual use, not 30 calendar days) so that you can test it thoroughly before purchasing a subscription.
