In the days of printing with metal type sorts, it was common to rotate letters and digits 180ð to create new symbols. This was a cheap way to extend the alphabet that didn't require purchasing or cutting custom sorts. The method was used for example with the Palaeotype alphabet, the International Phonetic Alphabet, the Fraser script, and for some mathematical symbols. Perhaps the earliest instance of this that is still in use is turned e for schwa.
In the eighteenth-century Caslon metal fonts, the British pound sign (ã) was set with a rotated swash uppercase J.
The following rotated (turned) letters have Unicode codepoints unless otherwise indicated.
In this table, parentheses mark letters that stand in for themselves or for another. For instance, a rotated 'b' would be a 'q', and indeed some physical typefaces didn't bother with distinct sorts for lowercase b and q, d and p, or n and u; while a rotated 's' or 'z' would be itself. Long s with a combining dot below, , can stand in for a rotated j.
(En dashes are used to mark small caps that would not be very distinct from the turned lower case letter, though they are possible: turned small cap c is supported, for example: ).
The Fraser script creates a number of duplicates of the rotated capitals.
<nowiki>*</nowiki>The Unicode character â  is specified as sans-serif, as are â  and â Â.
Other rotated letters include the digraphs á´ and á´Â. The "rotated" capital Q in Unicode is only turned 90 degrees: âº.
Additional small cap forms are found in the literature (e.g. turned ᴠàá´Â), but are not supported as of Unicode 17.
Many of the few rotated Greek letters are intended for mathematical notation. In this table, an en dash is used to mark Greek and Cyrillic letters that are not distinct from a Latin letter. Reversed L, , can stand in for a rotated gamma ÃÂ, though Unicode defines it as sans serif.
is close to the turned form of one variant of lower-case ÃÂ.
In some fonts, an allograph of ÷ displays as turned ã.
In addition, the turned Latin alpha and horseshoe of the IPA have allographs that are a turned small-capital àand é.
Other rotated symbols include à(rotated or reversed ÃÂ), à(rotated ÃÂ) â±¹ (rotated ý), ú (rotated ü), the digits â and âÂÂ, the insular g: ê¾ ê¿, and the ampersand â Â.
The turned comma or inverted comma () is, as its name suggests, a rotated comma. This symbol is most commonly encountered as an opening single quotation mark. It is also used for the Hawaiian letter âÂÂokina. In some older British texts, it was used as a superscript to abbreviate for the Scottish name element Mac/Mc, also written as M<sup>ac</sup>/M<sup>c</sup>, thus yielding , as in .
Spanish uses the rotated punctuation marks (inverted exclamation mark) and (inverted question mark).
In addition to turned letters, Unicode supports a few reversed (mirror-image) letters such as ÃÂ, ç è, ø ù, ÃÂ, á´Â, á´Â, ê», â  and ê¼; Cyrillic àà(reversed à÷) and ê ê¡ (as well as Cyrillic àø and ï ÃÂ, which are graphically equivalent to reversed Latin N ô and R ÃÂ), superscript ᶠᴻ, and the tresillo êª ê«, which historically is a reversed three. Current IPA àis officially a reversed rather than rotated ÃÂ; the older rotated á´ is now deprecated. àis close to a reversed Cyrillic ÃÂ. Reversed k á à  (ð¼ ð¼ ð¼Â) were added to the extIPA in 2015.
