QTextCodec / QStringConverter
https://doc.qt.io/qt-6/qstringconverter.html
https://doc.qt.io/qt-6/qtextcodec.html (Qt5Compat only, but afaict supports
more codecs)
You convert from the local 8-bit codec into UTF-8 when reading and back
from UTF-8 into the local codec when writing the file.
Internally you'll and want to operate on UTF-8.

There's no way to tell what a random 8-bit encoding actually is, all
implementations (eg. the unix "file" command) are purely heuristic.
They look around in the file for patterns that suggest one or the other
encoding and may guess correctly or be off by a mile.
(An exception is actually the - optional - unicode BOM)
