Title: [Fix] work with non-ascii filter word which can not be seperated by space

The file item filter, filter items by StringUtils::FindWords method.
but the StringUtils::FindWords method assume file labels is words separated by space, that's not true for non-ascii labels.
This pr will do a strstr like search for non-ascii filter word, and keep old behavior for ascii filter word.
