ignore C1 control characters in UTF-8 mode
Ignore processing and printing C1 control characters in UTF-8 mode.
These are in the range: 0x80 - 0x9f.
By default in st the mode is set to UTF-8.
This matches more the behaviour of xterm with the options -u8 or +u8 also.
Also see the xterm resource "allowC1Printable".
Let me know if this breaks something, in most cases I don't think so.
As usual a very good reference is:
