Unicode searching. Now you can.
For quite some time it has been possible to build a map using unicode to display characters in various languages.
Now searching should also work in versions r3294 and later.
All of Western, Central and Eastern European characters should be available as well as Arabic, Greek and various others. It is unlikely to work with Chinese characters and that will require further investigation.
Ensure that you are using the options
--code-page=65001 --index --route
as well any others that you need.
