I have forgotten to add the rest of the error message, but it is
identical to the first one post.

encoding error: output conversion failed two to conv error, bytes 0xE5
0x31 0x32 0xE5 I/O error: encoder error
Error: Given Error writing XML
Tails: -1

The string does not contain characters of control (es. LineFeed).
