Anyway, the very first paragraph has this:
ÄLMHULT, Sweden—Amid IKEA’s colorful staged living rooms, piles of umlaut-laden housewares and endless rows of flat-pack boxes is furniture that can have shoppers wondering: How does that chair cost only $35?
Which I think is really bad writing for a publication like the WSJ. Swedish does not have "umlauts". We have three letters more than the US English alphabet, but only two of them (Ä and Ö) have the double dots: the third has a ring (Å). These three are real first-class letters though, they are not "umlauted" (which means changed from some base letter due to grammar).
