Wrong languages used when using a DBList in an AWM app

To reproduce:

• Clean XS, not multilingual
• Create an AWM app with a DBList field (e.g. I've used XWiki.XWikiComments as class, and doc.fullName as id, and doc.title as value)
• Add a comment in Main.Sandbox
• Add an AWM entry and select "Bac a sable" (for me it's in French, not sure why, my wiki is in EN, the default)

Bug: when saving the entry, I get the Dblist value displayed in some asian language (looks korean)
