Connecting to an IRE MUD changes 'W' to a '￉'

The odd character here is coming up as Unicode point U+2592 "MEDIUM SHADE" - in Utf-8 that would be the three byte sequence 0xE2 0x96 0x92 or if utf-16 - which might translate to Qt internal format for QChar( 0x2592 ) but I'm not certain of that. Is this the actual character or has it been rewritten by being copied to here?

It is being rewritten, it should be a 'W' and was a 'W' in 2.1.

Um, no, what I meant was is that 50% grey (alternate pixel filled-in)
character what is actually being received in Mudlet or does it just
represent a replacement character put in somehow (as an alternative to
say '�', the 'proper' replacement character a.k.a. codepoint U+FFFD)
Reason I was asking was to see if there is any plusable way to get from
a single byte character to something that takes three bytes to encode.
One faint possibility might be that if the 'W' is the *very* *first*
byte of the incoming stream, if so, could the three bytes of a Byte
Order Mark - 0xEF,0xBB,0xBF be mixing up with the 0x57 for 'W' to
produce something weird...

That is a long shot though, and the mechanism causing it is beyond me at
the moment. I think we might need to know the OS and locale settings for
people having this bug - and some idea of who does not. (Beyond that
they are on 2.1)

I copied the character from Mudlet as-is, looks like it is U+FFC9 <not assigned>/

2.1 has no issue, 3.0.0-alpha people on all OS's are having this issue. You can test this fairly easily in both 2.1 and 3.0.0-alpha clients, see bug description for the test case.

Ah, so one of the errant bytes is a 0xFF - well THAT is Telnet IAC followed by 0xC9 (decimal 201 ???) which corresponds to GMCP doesn't it?

Yep

With 2.1, the telnet conversation looks like this (with GMCP turned off):

One side thing I noticed: 3.0 no longer respects the GMCP option in settings and enables it regardless of whether it's in the settings or not.

The bug reported here is fixed: https://github.com/Mudlet/Mudlet/pull/186
