Inside an editor plugin I'm running regex out of a Json file, like saved searches.
All works fine, except for high rank Unicode characters, for example I have :

{
      "case_sensitive": false, 
      "dot_all": false, 
      "find": "(‘)", 
      "mode": "regex", 
      "name": "LEFT SINGLE QUOTATION MARK REPLACE", 
      "replace": "'"
    },

Problem : this character is never found, even if I replace it with \u2018.
My Json file is Utf-8 encoded. I extract the pattern with :

pattern=unicode(searches["find"])

Even tried ur'pattern', nothing works.
I'm using the regex module and my compilation flags are : regex.VERSION1 | regex.WORD | regex.FULLCASE | regex.MULTILINE | regex.UNICODE

Same problem with all Unicode characters above \u2000.

Any idea to get it working ?
Thanks
