Basic usage
// Convert Traditional Chinese (Hong Kong) to Simplified Chinese (Mainland China)
const converter = OpenCC.Converter({ from: 'hk', to: 'cn' });
console.log(converter('漢語')); // output: 汉语
Custom Converter
const converter = OpenCC.CustomConverter([
['香蕉', 'banana'],
['蘋果', 'apple'],
['梨', 'pear'],
]);
console.log(converter('香蕉 蘋果 梨')); // output: banana apple pear
Or using space and vertical bar as delimiter.
const converter = OpenCC.CustomConverter('香蕉 banana|蘋果 apple|梨 pear');
console.log(converter('香蕉 蘋果 梨')); // output: banana apple pear
Add words
ConverterFactory
to create converter.Locale
.const customDict = [
['“', '「'],
['”', '」'],
['‘', '『'],
['’', '』'],
];
const converter = OpenCC.ConverterFactory(
OpenCC.Locale.from.cn, // Simplified Chinese (Mainland China) => OpenCC standard
OpenCC.Locale.to.tw.concat([customDict]) // OpenCC standard => Traditional Chinese (Taiwan) with custom words
);
console.log(converter('悟空道:“师父又来了。怎么叫做‘水中捞月’?”'));
// output: 悟空道:「師父又來了。怎麼叫做『水中撈月』?」
This will get the same result with an extra convertion.
const customDict = [
['“', '「'],
['”', '」'],
['‘', '『'],
['’', '』'],
];
const converter = OpenCC.ConverterFactory(
OpenCC.Locale.from.cn, // Simplified Chinese (Mainland China) => OpenCC standard
OpenCC.Locale.to.tw, // OpenCC standard => Traditional Chinese (Taiwan)
[customDict] // Traditional Chinese (Taiwan) => custom words
);
console.log(converter('悟空道:“师父又来了。怎么叫做‘水中捞月’?”'));
// output: 悟空道:「師父又來了。怎麼叫做『水中撈月』?」
