Typing diacritics (and other languages) into labels

Hi! i would really like to be able to type Vietnamese characters (like đ, ấ, ẵ, etc…) into labels, but even when the Vietnamese keyboard is enabled in my Mac settings, Audacity still uses my native keyboard input.

Copy-pasting the characters works but is cumbersome. Is there any way to get Audacity to accept the input as I type it? This used to be possible even a few years ago but doesn’t seem to work anymore.

Thanks very much.
