A build pass does indeed no longer surface this bug:
emiel@dev-001 ~/bun-repro> cat fr.ts
enum L {
Français = 'fr';
}
console.log(L.Français);
emiel@dev-001 ~/bun-repro> bun run fr.ts
undefined
emiel@dev-001 ~/bun-repro> bun build fr.ts > fr.js
emiel@dev-001 ~/bun-repro> bun run fr.js
fr
from bun.

It seems bun doesn't correctly parse non-ASCII characters in Typescript enum unless it's quoted.
enum TestEnum {
Δ = 'delta',
'Δ2' = 'delta as string',
'\u03943' = 'delta as code',
}
console.log(TestEnum.Δ);
console.log(TestEnum['Δ']);
console.log(TestEnum.Δ2);
console.log(TestEnum['Δ2']);
console.log(TestEnum.Δ3);
console.log(TestEnum['Δ3']);Result:
undefined
undefined
delta as string
delta as string
delta as code
delta as code
EDIT2:
This actually prints the value. I guess there's some issue on UTF-8 decoding on enum key handling?
console.log(TestEnum[unescape(encodeURI('Δ'))]);
// delta

$ cat unicode.ts
enum L {ç = "fr"};
console.log(JSON.stringify(L), L.ç, L["ç"]);
$ bun build unicode.ts | bun -
{"ç":"fr"} fr undefined
$ bun ./unicode.ts
{"ç":"fr"} undefined fr
