Problem with Events in French

Stange problem when I try to use regex in Extractor

I have 2 servers where I want to monitor Remote Desktop connections.

Server with **English language** works fine, full_message event come like this:

Remote Desktop Services: User authentication succeeded: User: REALM\username.name Domain: REALM Network Address: X.X.X.X

**With French Language:**

Services Bureau à distance : Ouverture de session réussie : Utilisateur : REALM\surname.name Domain: REALM Adresse réseau source : X.X.X.X

## Current Behavior
I try to extract the field USER, no problem in English but it seems that in French, the supposed space in full_message aren't really space character.

I already tried to use some convert function but without success.

## Steps to Reproduce (for bugs)
1. Try to extract $full_message of EventID 1149 in Windows Server 2012 R2 French
2. Extractor is in English : User: (\w+(\.\w+)?)
3. Extractor is in French : Utilisateur : (\w+(\.\w+)?) --> doesn't work
