Old Czech (Bohemian) or Moravian

Hehe, yes. My wife mixes up L and R sounds in English, because they're commonly interchangeable in in her native (Asian) spoken language. It's not the same in her written language, though - pronunciation is acceptably variable, but the spelling isn't.

Yes, written language is a whole different ballgame from spoken language.  I once had a job where I had to make frequent email communications with international customers.  I once had a long conversation with someone in Pakistan.  He (I assume he was a he) kept calling me "Mr."  I'm a Star Trek fan so I was okay with that.  He probably wasn't familiar with Western naming conventions.  He probably would have freaked out if he had learned he had been communicating with a woman.
