Features 特點

  • 嚴格區分「一簡對多繁」和「一簡對多異」。
  • 完全兼容異體字,可以實現動態替換。
  • 嚴格審校一簡對多繁詞條,原則爲「能分則不合」。
  • 支持中國大陸、臺灣、香港異體字和地區習慣用詞轉換,如「裏」「裡」、「鼠標」「滑鼠」。
  • 詞庫和函數庫完全分離,可以自由修改、導入、擴展。

int main() {
  const SimpleConverter converter("s2t.json");
  converter.Convert("汉字");  // 漢字
  return 0;


#include "opencc.h"

int main() {
  opencc_t opencc = opencc_open("s2t.json");
