NGUI Label, secondary term set with font ?

Hi I2 team !

I use I2 localization in my project !

For avoid missing keys I've added a log into GetTranslation method in case of after TryGetTranslation, the translation still null. (script : LocalizationManager_Translation.cs)
With this log I noticed that the Term is setted with NGUI font. I digged a little into your plugin and this is the secondary term that is setted with the font in the script LocalizeTarget_NGUI_Label.cs into the method GetFinalTerms.

Why did you set the secondaryTerm with the ambigiousFont ?

Thanks in advance,
Personne.
