Reproducing:
echo -ne "\033]0;Иq\007"
where first character after ';' is U+0418, D0 98, "Cyrillic Capital Letter
I".
The screen would first parse utf-8 char into an int, then put to the output
string only low 8 bits of the whole unicode character.
For the given letter, a weird control code would result, that tries to break
terminal (no header is set, instead garbage is printed).
Basing on bug #61032 and taking into account bug #66367, here is the patch for
5.0.0 codebase.
PS: this bug is common for UTF-8 directory names and a shell configured to put
current directory name into xterm window header through xterm OSC sequence.
