Glottal stop (letter)
From Wikipedia, the free encyclopedia
The symbol ʔ is a letter of the Latin alphabet, used to represent a glottal stop in several phonetic transcription schemes, as well as in the alphabets of some languages. A superscript version, ˀ, is also used.
Its shape is based on an enlarged curly apostrophe (ʼ)[citation needed] or spiritus lenis (᾿) with the symbol for the pharyngeal fricative being its mirror image (ʕ), based on the spiritus asper.
Where the glottal stop character is not available, it is sometimes replaced by a question mark (?), which is also its official representation in SAMPA.
In phonetic transcription as well as in several languages, a single, tall glyph is used in all situations, with no distinction between uppercase and lowercase. However, in the Chipewyan, Dogrib, and Slavey languages, the tall version is only used for the uppercase, and a short version is used for the lowercase.

[edit] Computer encoding
In Unicode 1.0, only the tall version and superscript version were included. In version 4.1 (2005), an uppercase character was added, and the existing tall glottal stop was redefined as its lowercase. Finally, in version 5.0 (2006) it was decided to separate the cased and caseless usages, assigning separate characters to each. The rationale for this decision can be found here.
