Another concern: If your app/website is available in a language, customers will expect support in that language.

I've had lots of support conversations where the customer is typing in their own language while I type in English. Google Translate isn't perfect but it gets the ideas across well enough that we can usually resolve their issue.

I do this over Facebook Messenger at least once per fortnight.
