ActiveX controls are not foxpro and therefore have no controlsource property usable as with a vfp control. You would need do programmatical what VFp does automatic if you use an ActiveX textbox.
MrDataGuy already pointed you to the right resource for application internationalisation: INTL Toolkit.
You don't need UTF-8 or unicode data to support other languages including japanese and chinese, arabic etc. They all can be supported by some ANSI codepage specifically for them - Very many languages using the latin alphabet can even be support with only one codepage 1252 for these languages.
