I was wondering if the beta checkbox the same thing as setting the ActiveCodePage to UTF-8 in the manifest, but the docs[0] clarify that GDI doesn't adhere to per-process codepage, but only a single global one, which is what the checkbox sets.

Bit of a shame that you can't fully opt-in to be UTF-8 with the *A API, for your own apps. But I think for the issues highlighted in the post, I think it would still be a valid workaround/defence-in-depth thing.
