okina (オキナ)
オキナ （ハワイ語を正しく発音する為のアポストロフィーに似たマーク）
このマーク→「`」 ASCII value 96 in decimal and 60 in hexadecimal
The ‘okina is the Hawaiian apostrophe-like character used to indicate the glottal stop consonant.
It is properly represented by a glyph identical to an opening left single quotation mark, that is,
with the appearance (‘). The name of the island group itself in Hawaiian includes the mark,
thus, Hawai‘i.
In plain ASCII the ‘okina is sometimes represented by the apostrophe character ('),
ASCII value 39 in decimal and 27 in hexadecimal, which in most fonts currently used renders as
a straight, data-processing, typewriter apostrophe as is also specified in Unicode.
But in some older fonts, especially those used on Unix platforms and related platforms and on
an MS-DOS screen it renders as a right single quotation mark (which is the wrong shape).
A more pedantic and ultra-correct method for plain ASCII text is to use the grave accent
character (`), ASCII value 96 in decimal and 60 in hexadecimal, which in some older fonts,
especially those used on older Un*x platforms, does display a glyph similar to a left single
quotation mark.
