Prokosch describes the symbol as a "modified ''h'', since ''h'' is the usual spelling in all Germanic languages" (p. 83), though other authors simply write these sounds '.
*superscript spacing diacritic , used to indicate clicks in Smalley (1963)
Several symbols are graphic variants of characters that are supported by Unicode:
*hooktop j, an Americanist variant of in Smalley (1963) ''Manual of Articulatory Phonetics''. Unlike , in the Smalley letter the hook connects to the dot of the jay and so is detached from the body of the letter.
