这是我发现的一个网站，可以生成任何英文文本的颠倒版本。

它是如何工作的？unicode 有颠倒的字符吗？或者是什么？

如何编写自己的文本翻转功能？

它是如何工作的？unicode 有颠倒的字符吗？

Unicode确实有颠倒的字符。他们的名字中有“TURNED”：

ƍ U+018D LATIN SMALL LETTER TURNED DELTA
Ɯ U+019C LATIN CAPITAL LETTER TURNED M
ǝ U+01DD LATIN SMALL LETTER TURNED E
Ʌ U+0245 LATIN CAPITAL LETTER TURNED V
ɐ U+0250 LATIN SMALL LETTER TURNED A
ɒ U+0252 LATIN SMALL LETTER TURNED ALPHA
ɥ U+0265 LATIN SMALL LETTER TURNED H
ɯ U+026F LATIN SMALL LETTER TURNED M
ɰ U+0270 LATIN SMALL LETTER TURNED M WITH LONG LEG
ɹ U+0279 LATIN SMALL LETTER TURNED R
ɺ U+027A LATIN SMALL LETTER TURNED R WITH LONG LEG
ɻ U+027B LATIN SMALL LETTER TURNED R WITH HOOK
ʇ U+0287 LATIN SMALL LETTER TURNED T
ʌ U+028C LATIN SMALL LETTER TURNED V
ʍ U+028D LATIN SMALL LETTER TURNED W
ʎ U+028E LATIN SMALL LETTER TURNED Y
ʞ U+029E LATIN SMALL LETTER TURNED K

ʯ U+02AF LATIN SMALL LETTER TURNED H WITH FISHHOOK AND TAIL
ʴ U+02B4 MODIFIER LETTER SMALL TURNED R
ʵ U+02B5 MODIFIER LETTER SMALL TURNED R WITH HOOK
ʻ U+02BB MODIFIER LETTER TURNED COMMA
̒ U+0312 COMBINING TURNED COMMA ABOVE
ჹ U+10F9 GEORGIAN LETTER TURNED GAN
ᴂ U+1D02 LATIN SMALL LETTER TURNED AE
ᴈ U+1D08 LATIN SMALL LETTER TURNED OPEN E
ᴉ U+1D09 LATIN SMALL LETTER TURNED I
ᴔ U+1D14 LATIN SMALL LETTER TURNED OE
ᴚ U+1D1A LATIN LETTER SMALL CAPITAL TURNED R
ᴟ U+1D1F LATIN SMALL LETTER SIDEWAYS TURNED M
ᵄ U+1D44 MODIFIER LETTER SMALL TURNED A
ᵆ U+1D46 MODIFIER LETTER SMALL TURNED AE
ᵌ U+1D4C MODIFIER LETTER SMALL TURNED OPEN E
ᵎ U+1D4E MODIFIER LETTER SMALL TURNED I
ᵚ U+1D5A MODIFIER LETTER SMALL TURNED M
ᵷ U+1D77 LATIN SMALL LETTER TURNED G
ᶛ U+1D9B MODIFIER LETTER SMALL TURNED ALPHA
ᶣ U+1DA3 MODIFIER LETTER SMALL TURNED H
ᶭ U+1DAD MODIFIER LETTER SMALL TURNED M WITH LONG LEG
ᶺ U+1DBA MODIFIER LETTER SMALL TURNED V
℩ U+2129 TURNED GREEK SMALL LETTER IOTA
Ⅎ U+2132 TURNED CAPITAL F
⅁ U+2141 TURNED SANS-SERIF CAPITAL G
⅂ U+2142 TURNED SANS-SERIF CAPITAL L
⅄ U+2144 TURNED SANS-SERIF CAPITAL Y
⅋ U+214B TURNED AMPERSAND
ⅎ U+214E TURNED SMALL F
⌙ U+2319 TURNED NOT SIGN
❛ U+275B HEAVY SINGLE TURNED COMMA QUOTATION MARK ORNAMENT
❝ U+275D HEAVY DOUBLE TURNED COMMA QUOTATION MARK ORNAMENT
⦢ U+29A2 TURNED ANGLE
Ɐ U+2C6F LATIN CAPITAL LETTER TURNED A
ⱹ U+2C79 LATIN SMALL LETTER TURNED R WITH TAIL
ⱻ U+2C7B LATIN LETTER SMALL CAPITAL TURNED E
Ꝿ U+A77E LATIN CAPITAL LETTER TURNED INSULAR G
ꝿ U+A77F LATIN SMALL LETTER TURNED INSULAR G
Ꞁ U+A780 LATIN CAPITAL LETTER TURNED L
ꞁ U+A781 LATIN SMALL LETTER TURNED L

然而，它远非完整的一套。大多数颠倒文本通过选择恰好与颠倒字母非常相似的字符来工作。这相当于在计算器上输入 0.7734 来拼写“你好”。

unicode 有颠倒的字符吗？

是的！或者至少看起来像是颠倒的字符。此外，常规的英文字母字符可能看起来是颠倒的。就像u可能是一个颠倒的n。

要对其进行编码，您只需获取一个字符数组，以相反的顺序显示它们，然后用它们的颠倒版本替换这些字符。这会给你一个好的开始：zʎxʍʌnʇsɹbdouɯןʞſıɥbɟǝpɔqɐ

当 'uʍop-ǝpısdn' 被复制并回显到十六进制转储程序中时，字符串被视为：

75 CA 8D 6F 70 2D C7 9D 70 C4 B1 73 64 6E

UTF-8 的分解是：

0x75      = U+0075 = LATIN SMALL LETTER U
0xCA 0x8D = U+028D = LATIN SMALL LETTER TURNED W
0x6F      = U+006F = LATIN SMALL LETTER O
0x70      = U+0070 = LATIN SMALL LETTER P
0x2D      = U+002D = HYPHEN MINUS
0xC7 0x9D = U+01DD = LATIN SMALL LETTER TURNED E
0x70      = U+0070 = LATIN SMALL LETTER P
0xC4 0xB1 = U+0131 = LATIN SMALL LETTER DOTLESS I
0x73      = U+0073 = LATIN SMALL LETTER S
0x64      = U+0064 = LATIN SMALL LETTER D
0x6E      = U+006E = LATIN SMALL LETTER N

查看网页来源：

function flip() {
    var result = flipString(document.f.original.value);
    document.f.flipped.value = result;
}

function flipString(aString) {
    aString = aString.toLowerCase();
    var last = aString.length - 1;
    var result = "";
    for (var i = last; i >= 0; --i) {
        result += flipChar(aString.charAt(i))
    }
    return result;
}

function flipChar(c) {
    if (c == 'a') {
        return '\u0250'
    }
    else if (c == 'b') {
        return 'q'
    }
    else if (c == 'c') {
        return '\u0254' //Open o -- copied from pne

有一个“颠倒”的python模块。https://pypi.org/project/upsidedown/。它也支持非英文字符。
