I have an app that I am converting that only has ENU (en-US) captions. I want to deploy into the United Kingdom (ENG/en-GB). I generate the XLF file and it has all the ENU captions in it. However Lifecycle Services Translation Services does not have the ability to convert from en-US (source) to en-GB (or any en-?? as Target).
As I am sure you are aware, there are many minor differences in spelling (labor vs. labour, License vs. Licence, etc.) and while minor are important. Will there be a time when en-GB (and other en-??) is available as a Target language?
