When I use the copy button that appears when you hover over a response, it fails to copy the raw LaTeX code that is behind any rendered LaTeX. Instead it copies some strange character that is not in the GSM charset.
The following character between the curly brackets is what is copied when E=mc^2 is rendered: {}.
This does not occur in the website version.
Below is a screenshot of my testing prompt in the macos app.
Website version:
Testing 123 --- \( E = mc^2 \) --- Testing 456
MacOS version:
Testing 123 —  — Testing 456
(i guess the macos version also replaces
---
by —
)
I came across this issue whilst submitting a bug report for another LaTeX related issue in the mac app (#1099574).
I am on chatgpt macos version: 1.2025.009 (1737138094)
