Japanese half / full width conversion

Question

I ran into the problem of character width in Japanese using glib :: ustring.

I have this line: ウ ェ ッ ジ パ ン プ ス

I want to convert it to: ウ エ ッ シ パ ン プ ス

Using ustring :: normalize, I get this line: ウ ェ ッ ジ パ ン プ ス (in fact, each character with an accent fills the width of two characters)

Is there a standard method for handling this kind? Is OIT more effective?

I need to convert Japanese strings to one of two formats because a half-width string is different from the same width.

Answer 1

LCMapString, / hiragana/katakana

AnsiString text = "変換する文字列"; //input text
//変換方法 how to convert
DWORD flags = LCMAP_FULLWIDTH; //全角文字にします。flag to convert to full width
//DWORD flags = LCMAP_HALFWIDTH; //半角文字にします）。to half width
//DWORD flags = LCMAP_HIRAGANA; //ひらがなにします。to hiragana
//DWORD flags = LCMAP_KATAKANA; //カタカナにします。to katakana
const int size = text.Length() * 2 + 1;
char* s = new char[size];
try
{
  ZeroMemory(s, size);
  LCMapString(GetUserDefaultLCID(),
              flags,
              text.c_str(),
              text.Length() + 1,
              s,
              size);
  AnsiString newtext = s; //変換した文字列 converted text
  return newtext;
}
