I'm parsing the results from a hierarchical database query to make it compatible with another hierarchical database. Specifically, I'm parsing user created notes from a pipe-delimited CSV that was translated from the query result. Everything runs smoothly. I send my output to be processed through our batch system. Everything checks out as expected.

A couple blank notes throw exceptions, but I knew that was going to happen. Then suddenly, I read "Cannot create note with unprintable characters"
Okay?

Somehow this person had been able to type the Ash (æ) character and an accented A (à) this came from a system that didn't even support characters outside of alphanumerics. How?
