For example, you wouldn't think twice about it if for the Japanese word for washing machine, you not only saw "洗濯機" (which is how it's written in Kanji), but also "sentakuki" or "sentakki" in the search results, because even to non-Japanese speakers it's pretty clear that that's probably the Japanese word for washing machine written with latin character transliteration, and pretty much exactly what you'd say.
With Korean, it looks more jarring, as the input method is apparently very different, and seems to map the keys for unrelated latin letters to Hangul letters? (I have no idea, I don't know anything about Hangul other than it's based on syllables, kind of like Hiragana/Katakana, and apparently very logical.)
