Different conventions exist for the treatment of subscript/adscript iota with uppercase letters. In Western printing, the most common practice is to use subscript diacritics only in lowercase environments and to use an adscript (i.e. a normal full-sized iota glyph) instead whenever the host letter is capitalized. When this happens in a mixed-case spelling environment (i.e. with only the first letter of a word capitalized, as in proper names and at the beginning of a sentence), then the adscript iota regularly takes the shape of the normal lowercase iota letter (e.g. → ). In an all-capitals environment, the adscript is also regularly capitalized (). In Greece, a more common convention is to print subscript diacritics both with lowercase and uppercase letters alike. Yet another, intermediate convention is to use lowercase adscript iotas both for mixed-case and for all-capitals words (e.g. ), or to use a special glyph in the shape of a smaller capital iota in the latter case ().
