I'm aware of the "metal umlaut" meme, but as a German native speaker, I can't not read these in my head in a way that sounds much less Metal than probably intended :)

Years ago, an American metalhead was added to a group chat before she came to visit.

She was called Daniela, but she'd written it "Däniëlä". When my Swedish friend met her in person, havin seen her name in the group chat, he said something like "Hej, Dayne-ee-lair right? How was the flight?".

The best metal umlauts are placed on a consonant (e.g., Spın̈al Tap). This makes it completely clear when it's there for aesthetics and not pronunciation.

I will always pronounce the umlaut in Motörhead. Lemmy brought that on himself.

Yes, those umlauts made it sound more like a fake french accent.

It can encode Spın̈al Tap, so it's all good.
