Description XiJet Gary Guan 2025-07-25 09:02:51 UTC

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.)

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.
