Browser copy-paste corrupts diff patches while curl works fine

Problem

If I go to the .diff url for an MR, manually copy all the text of the diff, then in the terminal pbpaste | git apply , I'll sometimes get a corrupt patch error. But if I curl [url of diff] | git apply for the same url, it works.

Steps to reproduce

The specific url where I just had this happen was !181052.diff

1. go to !181052.diff in the browser
2. select all and copy
3. go to the GDK's gitlab subrepo directory, pbpaste | git apply
4. get a corrupt patch error
5. instead, in the same directory, run curl !181052.diff | git apply
6. that works

181052.diff.txt

Initial troubleshooting

Removing this part of the diff worked fine

diff --git a/locale/gitlab.pot b/locale/gitlab.pot
