Bugzilla

When running the libwebrtc update scripts on the Mozilla git repo, we generated a set of patches were pushing to try fails.  I've been able to distill the patches down to 2 patches where we're adding and then modifying a patch file under third_party/libwebrtc/moz-patch-stack.  The patch files that directory are generated by using the `git format-patch` command.  It seems to be related to non-ASCII characters in the patch file.

For historical purposes, the try command I'm using to test this is ```./mach try fuzzy --full -q '^source-test-mozlint-py-ruff'```, but the issue happens with other query strings.

The email I get from Lando states:
Your request to land try push with tip commit 'WIP: Vendor libwebrtc from 6cccb107b8' failed.

Reason:
Problem while applying patch in revision None:
