Or at least 'Huegelkultur', especially since the author spends some time talking about the correct spelling.

I copied and pasted the title when I submitted it. The mods modified it to have the first letter capitalized even though it is not in the article. My mom is German and I know a smidgeon, though I would not say I am fluent. I quoted the part of the article where the author says they can't pronounce it.

So in this case, I think it does not work to add the umlaut. It may be more correct German but it does not accurately represent the article. As a half German American, I appreciate some of the comments on the language piece in this discussion but I can't agree with your request here.

But where do you start? :)

Even most news outlets can’t even get their micro-typography right in the age of Unicode.

It is ‟Foo”, not "Foo". In languages where quotes are on the baseline, e.g. German, this is even more of an eyesaw. "Spiegel" instead of „Spiegel“ (to make matters worse, the German closing quote is wrong in Verdana, somehow). And let’s not start about - vs. – vs. — or the difference between ... and … (and that you have to put a space before an ellipsis). :)

You start where, to a native speaker, you might not even get what the word means - because u and ü are not nitpicking, but different letters.

Let's take the example of "fordern" vs "fördern" - nothing in common, the former means "to demand" and the latter means "to promote/boost/foster".
