How do you type ー in words like タクシ一?
How do you type ー? I typed いち and selected the 一 but Duolingo said it was the incorrect character. Why?
My first thought was what Arachnje stated, simply type a dash and the IME will convert it. Thing is, while "一" and "ー" look the same, they are actually different unicode characters. The first is the kanji for 1 (いち), while the second is the long vowel character in e.g. 「フォーク」(fo-ku/fork). So if you have to type the long vowel character, simply type '-' (as mentioned by Arachnje) and don't type いち as it is a "different dash" =)
