[edit] Example
Run this code
#include <locale.h> #include <wctype.h> #include <wchar.h> #include <stdio.h> int main(void) { setlocale(LC_ALL, "ja_JP.UTF-8"); const wchar_t kana[] = L"ヒラガナ"; size_t sz = sizeof kana / sizeof *kana; wchar_t hira[sz]; for (size_t n = 0; n < sz; ++n) hira[n] = towctrans(kana[n], wctrans("tojhira")); printf("katakana characters %ls are %ls in hiragana\n", kana, hira); }
Output:
