5. Usage​

Character encoding conversion​

// Convert UTF-8 encoded string to GBK encoded arraybuffer
let res = iconv.convert("utf-8", "gbk", "你好", iconv.DATA_TYPE.STRING, iconv.DATA_TYPE.ARRAY_BUFFER)
log.info("Convert UTF-8 encoded string to GBK encoded arraybuffer: " + common.arrayBufferToHexString(res))

// Convert GBK encoded arraybuffer to UTF-8 encoded string
res = iconv.convert("gbk", "utf-8", res, iconv.DATA_TYPE.ARRAY_BUFFER, iconv.DATA_TYPE.STRING)
log.info("Convert GBK encoded string to UTF-8 encoded string: " + res)

// Convert UTF-8 encoded string to ISO-8859-1 encoded arraybuffer
res = iconv.convert("utf-8", "iso-8859-1", "hello", iconv.DATA_TYPE.STRING, iconv.DATA_TYPE.ARRAY_BUFFER)
log.info("Convert UTF-8 encoded string to ISO-8859-1 encoded arraybuffer: " + common.arrayBufferToHexString(res))

// Convert ISO-8859-1 encoded arraybuffer to UTF-8 encoded string
res = iconv.convert("iso-8859-1", "utf-8", res, iconv.DATA_TYPE.ARRAY_BUFFER, iconv.DATA_TYPE.STRING)
log.info("Convert ISO-8859-1 encoded string to UTF-8 encoded string: " + res)
