Golang emoji parser
License: Other
This Package emoji is designed to recognize and parse every individual Unicode Emoji characters from a string.
func main() {
s := "👩👩👦🇨🇳"
i := 0
final := emoji.ReplaceAllEmojiFunc(s, func(emoji string) string {
i++
fmt.Printf("%02d - %s - UTF-8 len %d\n", i, emoji, len(emoji))
return fmt.Sprintf("%d-", i)
})
fmt.Printf("final: <%s>\n", final)
}
// Output:
// 01 - 👩👩👦 - UTF-8 len 18
// 02 - 🇨🇳 - UTF-8 len 8
// final: <1-2->
打比方unicode文档内的标识是：
1F191..1F19A ; Basic_Emoji ; CL button # E0.6 [10] (🆑..🆚)
而你生成出来的只有2个，实际上源文档内这里有10个符号：
AllSequences.AddSequence([]rune{0x1f191}, "Basic_Emoji ==> 🆑")
AllSequences.AddSequence([]rune{0x1f191, 0xfe0e}, "Basic_Emoji ==> 🆑")
AllSequences.AddSequence([]rune{0x1f19a}, "Basic_Emoji ==> 🆚")
AllSequences.AddSequence([]rune{0x1f19a, 0xfe0e}, "Basic_Emoji ==> 🆚")
有很多符号都匹配不了，比如 🎵 这个
红心表情有两个，❤️[表情符号]和❤[文字符号]
文字符号版本在当前库版本下无非被正确识别替换。
其原因我有研究是因为红心在 emoji 诞生前就存在于 unicode 编码中，老的编码短的那个
0x2764 ❤
老的在新版本还有个编码
0x2764 0xFE0E ❤
新版本的编码是这样：
0x2764 0xFE0F ❤️
我还找到了 unicode 编码官网，它的emoji-sequences.txt同样只有新的编码，在旧版本中存在0x2764老编码。
https://www.unicode.org/Public/emoji/15.1/emoji-sequences.txt
但我没研究明白，如何让这个库兼容旧的红心❤识别。
还有对两个两种红心编码的文字定义介绍:

期待这个库能够提供兼容的方案
