Translation Alert notification Registration

Hi,

I think there is an issue about the translation of Alert notification on Username and Password fields (with Registration Integration actived).
I can't translate "characters required" (the constant for this value is not available in osmembership translation file).
I attach two screenshots.






I tried also to translate the file language about jquery.validationEngine

"minSize": {
"regex": "none",
"alertText": "* Minimum ",
"alertText2": " characters required"
},

but without success.

I'm waiting for your suggestion.

Thank you!

Pascal
