}What issue are you seeing?
Codex cause broken string when editing my vuejs source. I use vietnamese text string and Codex turned them into mojibake. This issue happened over and over again though I told codex to write itself the md to not violate the problem again. But it did many times.
It just burn my limits, credits and made errors
What steps can reproduce the bug?
Just tell it to fix any vuejs template files containing vietnamese and it's gonna turn them to mojibake.
What is the expected behavior?
No mojibake anymore
