uʍop-ǝpᴉsdn 文本如何工作？

Question

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。

它是如何实现的工作？ unicode有颠倒的字符吗？或者什么？

如何编写自己的文本翻转功能？

Answer 1

它是如何工作的？ unicode 有吗
颠倒的字符？

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

ǝ U+01DD LATIN SMALL LETTER TURNED E
Ʌ U+0245 LATIN CAPITAL LETTER TURNED V

❛ 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+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，它还远不是一个完整的集合。大多数颠倒文本的工作原理是选择与颠倒字母非常相似的字符。这相当于在计算器上输入 0.7734 来拼写“hELLO”。

Answer 2

unicode有颠倒的字符吗？

是的！或者至少是看起来像是颠倒的角色。此外，常规的英文字母字符可能看起来是颠倒的。就像u可以是颠倒的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，并将这些字符替换为它们的颠倒版本。这会给你一个好的开始：zʎxʍʌnʇsɹbdouɯןʞſıɥbɟǝpɔqɐ

Answer 3

当“uʍop-ǝpısdn”被复制并回显到十六进制转储程序时，该字符串将被视为：

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

其 UTF-8 细分为：

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

Answer 4

它们只是 unicode 字符。

Answer 5

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

Answer 6

有一个“颠倒的”Python 模块。 https://pypi.org/project/upsidedown/。它也支持非英文字符。源代码：https://github.com/cburgmer/upsidedown。问题已经回答了多次，但坚持规则：没有魔法，字符串的字符被字符替换 - 或多或少类似于倒置的字符。您可以使用 sed:

echo "abc" | sed 's/a/ɐ/g; s/b/q/g; s/c/ɔ/g'

构建字典，

或更好的方法 - 为 sed: script.sed:

s/a/ɐ/g
s/b/q/g
s/c/ɔ/g

然后：

echo "abc" | sed -f script.sed

然后“仅”反转顺序。

附言。还有另一个带有颠倒文本生成器的网站：

Answer 7

有些 Unicode 字符看起来与普通字母相似，并且是倒转的，例如：B 的倒转版本可以是“ᗺ”，它是加拿大音节载体 Kha 字符 (U+15FA)，此网站 https://www.upsidedowntext.top/ 包含用于生成颠倒文本的所有反转 Unicode 字符的列表。

如需更多说明，您可以查看此字体生成器网站 https://fontgenerator.cc/，它创建了许多其他花哨的字体使用不同 Unicode 字符的样式。

您可以通过使用普通字母表作为键、使用 Unicode 字符作为值来初始化映射来实现此目的。之后，您所要做的就是获取用户输入并将每个输入字符转换为映射中对应的 Unicode 字符值。

  "upsideDown": {
    "A": "Ɐ",
    "B": "ᗺ",
    "C": "Ɔ",
    "D": "ᗡ",
    "E": "Ǝ",
    "F": "Ⅎ",
    "G": "⅁",
    "H": "H",
    "I": "I",
    "J": "ᒋ",
    "K": "ꓘ",
    "L": "⅂",
     ....
     }
