UAO-js

An UAO encoder/decoder.

Features

• Encode/decode string with UAO table.

Install

npm install --save uao-js

Usage

var uao = require("uao-js");

uao.encode(unicodeString).then(binaryString => {
	// ...
});
uao.decode(binaryString).then(unicodeString => {
	// ...
});

// Sync
binaryString = uao.encodeSync(unicodeString);
unicodeString = uao.decodeSync(binaryString);

.encode, .encodeSync will raise an error for unencodable characters. To suppress the error, feed a replacement character:

uao.encode(unicodeString, "?");

For undecodable characters, .decode leaves them as-is.

API

encode(text, createTable): Promise

encodeSync(text, createTable): binaryString

decode(binaryString, errorReplacement, createTable): Promise

decodeSync(binaryString, errorReplacement, createTable): text

createTable is a function that should return a unicode-to-big5/big5-to-unicode table. You may want to implement your own table loader in some environment which can't use require to load json.
