前幾天剛好有需求要把emoji對應的Unicode編碼轉(zhuǎn)換成文字，比如1f601對應的這個笑臉😁，但沒有找到C#的把1f601轉(zhuǎn)換成文字的方法，用Encoding.Unicode怎么轉(zhuǎn)換都不對，最后直接復制emoji字符，Visual Studio里面竟然直接顯示出來了，那就直接用字符吧，都不用轉(zhuǎn)換了，然后不了了之了。

今天搞Markdown編輯器，由于前面GFM的原因，又對編碼進行測試，沒查到什么靠譜資料，到時找到很多emoji和Unicode對照表，https://apps.timwhitlock.info/emoji/tables/unicode拿一個笑臉https://apps.timwhitlock.info/unicode/inspect/hex/1F601開刀~

【C#】

Encoding.UTF32.GetBytes('😁') -> ['1', 'f6', '1', '0']

【js】

'😁'.codePointAt(0).toString(16) -> 1f601

【java】

byte[] bytes = '😀'.getBytes('utf-32'); System.out.println(getBytesCode(bytes)); private static String getBytesCode(byte[] bytes) { String code = ''; for (byte b : bytes) { code += 'x' + Integer.toHexString(b & 0xff); } return code; }

UTF-32結(jié)果一致

【C#】

Encoding.UTF8.GetBytes('😁') -> ['f0', '9f', '98', '81']

【js】

encodeURIComponent('😁') -> %F0%9F%98%81

UTF-8結(jié)果一致

【js】

String.fromCodePoint(’0x1f601’) utf-32

【java】

String emojiName = '1f601'; //其實4個字節(jié) int emojiCode = Integer.valueOf(emojiName, 16); byte[] emojiBytes = int2bytes(emojiCode); String emojiChar = new String(emojiBytes, 'utf-32'); System.out.println(emojiChar); public static byte[] int2bytes(int num){ byte[] result = new byte[4]; result[0] = (byte)((num >>> 24) & 0xff);//說明一 result[1] = (byte)((num >>> 16)& 0xff ); result[2] = (byte)((num >>> 8) & 0xff ); result[3] = (byte)((num >>> 0) & 0xff ); return result; }c# 漢字和Unicode編碼互相轉(zhuǎn)換實例
