Is it possible to set -codepage compiler flag?

Hi,

I work with multiple teams across East Asia that have a wide variety of setups and would like to enforce UTF-8 source files. On windows, however, unless otherwise specified, mono seems to use the default OEM codepage, which is usually anything but UTF-8. Including a BOM in the source file forces proper detection of UTF-8, however it gets forgotten from time to time, so so far I've set up detection in CI, but that feels only like a stopgap measure.

1. Is it possible to directly set compiler flags - specifically -codepage:utf8 - from Unity?

2. Is there maybe a better way to support this environment?

Thanks.
