How does uʍop-ǝpᴉsdn text work?

Question

Here\'s a website I found that will produce upside down versions of any English text.

how does it work? does unicode have upside down chars? Or what?

How can

Answer 1

When 'uʍop-ǝpısdn' is copied and echoed into a hex dump program, the string is seen as:

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

The UTF-8 breakdown of that is:

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
