...I've had the same thing happen in emails. Heard a story a long time ago about a man who worked for [I think] I.B.M. He lived in a small welsh village that had an apostrophe in the middle of its name.
Just to upset his I.T. dept. he made a point of complaining that every time his address was printed out, strange things would occur in place of the apostrophe. There was a kerfuffle when they 'corrected' this by changing his details on file so that the apostrophe was removed - that was, they said, the best they could do.
He didn't accept this and carried on complaining that the name of his village was incorrectly spelled.
Don't think they ever worked it out.
