* BOMs have priority. If a BOM is present, the encoding set by the BOM
is used.
* if no BOM is present, then TMerge scans the file for invalid utf8
sequences. If such an invalid sequence is found, ASCII encoding is used
* if no BOM is present and no invalid utf8 sequence is found, the utf8
encoding is used.

In case you're wondering what an invalid utf8 sequence is:
