            Bug ID: 507472
           Summary: Output stop unexpectedly when garbled character, which
                    different from other virtual terminal.
    Classification: Applications
           Product: konsole
      Version First 25.04.3
       Reported In:

SUMMARY
When software outputs garbled characters, then output will terminate
unexpectedly, not due to crash, but rather that then subquent output is not
displayed.

STEPS TO REPRODUCE
1. `touch 123$'\302\204\302\236'456`
2. `ls | cat`

OBSERVED RESULT
Output stop when it come to the file we create. (123$'\302\204\302\236'456).
In some software, it will keep outputting file names, but stop when output this
file's name, it can be recovered by pressing Ctrl-Z then `fg` it. (My Shell is
Fish, but Bash seem work in this way.)

EXPECTED RESULT
Continue output after then garbled char. As Gnome-terminal or Linux TTY. (Even
though those two software have different behavior.)

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 6.15.7-zen1-1-zen (64 Bit)
KDE Plasma Version: 6.4.3
KDE Frameworks Version: 6.16.0
Qt Version: 6.9.1

ADDITIONAL INFORMATION
The garbled filename was found in the game file, I can't damage the integrity
of the game just to alleviate this problem, however, it's really affecting my
usage.

inappropriate.)
