In English we already have naïve, coöperate, reëlect as perfectly acceptable, if somewhat old-fashioned spellings. So I'd argue the look at least of Türkiye [1] is not as foreign as the two examples you gave :) [1] Admittedly the diacritic is an umlaut not diaeresis, but I take your point to be about the (supposedly) foreign appearance of Türkiye.
