Looking to understand what types of problems and experiences you have related to language - anywhere from international customer service, multi-lingual teams, interacting with vendors/suppliers, and etc.
Currently doing design research for a project, so I'd love to hear about what problems you face.
This is only partially a language problem. Differences in culture and regulations, tax laws etc. play a large role as well, which really is a shame because that's what the EU to a large part is about: Removing regulatory barriers in order to allow for a single European market.
So unfortunately, it's not as easy as just getting i18n right, although that's still not an exactly easy-to-solve problem in its own right.
