kotlinで平仮名をカタカナにしたい

Posted at

文字列の平仮名をカタカナに置き換えます。
特に難しくないので詳しくは書きません。

コード

object JpConverter{
    fun hiraToKata(str: String) = 
        str.map { 
            if (it.code in 0x3041..0x3093) {
                it + 0x60 
            } else {
                it
            } 
        }.joinToString("")
}

it + 0x60だけつまづきました。it + "0x60"と書いたら動かなかったので、、

最後に

ミスは指摘お願いします。
もっといい方法あれば教えてください。
