FOR ALL, UP TACK, DIGIT NINE: what Upside Down characters are called

No font is turned over here. Each changed key gives a different Unicode character that has its own name and code point, and many of the names are not a letter's: a typed A becomes U+2200, FOR ALL, a symbol.

The 48 characters are gathered from twelve blocks:

• IPA Extensions: 12
• Basic Latin: 10
• Latin Extended-B: 6
• Mathematical Operators: 4
• Letterlike Symbols: 4
• Greek and Coptic: 3
• Unified Canadian Aboriginal Syllabics: 2
• Phonetic Extensions: 2
• Bopomofo: 2
• Latin Extended-A: 1
• Cyrillic Supplement: 1
• Hangul Compatibility Jamo: 1

Last character first

Upside Down reverses your text. The characters come out in reverse order, so the last one you typed stands first.

Forty-eight Upside Down characters and one run of two

The changed keys are 19 capitals, 21 small letters and 8 digits. Their code points are scattered. Taken in key order, no changed capital or digit is followed by the next code point: each is a run of one. Among the small letters only v and w make a run of two, U+028C and U+028D.

b and q, d and p, n and u change places

Six small letters come out as another plain letter of the alphabet: b gives q and q gives b, d gives p and p gives d, n gives u and u gives n. The result is the ordinary character, so a typed b is U+0071, LATIN SMALL LETTER Q. M and W do the same among the capitals, and 6 and 9 among the digits.

Three more small letters are exceptions to the main block of their group, which holds 12 of the 21: e and i get LATIN SMALL LETTER TURNED E and LATIN SMALL LETTER TURNED I, and g gets U+0183, LATIN SMALL LETTER B WITH TOPBAR.

Fourteen keys come back as typed

Upside Down leaves 14 keys as they are.

• Capitals: H, I, N, O, S, X, Z
• Small letters: l, o, s, x, z
• Digits: 0, 8

Twenty punctuation marks change with the letters

Brackets trade sides: a left parenthesis, square bracket or curly bracket becomes the right one and the right one becomes the left, and the less-than and greater-than signs do the same. A comma and an apostrophe become each other. A question mark becomes INVERTED QUESTION MARK, an exclamation mark INVERTED EXCLAMATION MARK and an ampersand TURNED AMPERSAND.
