Assume you're talking about composing the input string (though the same string, composed and decomposed, would be shaped into the same sequence of glyphs). A while ago we decided to not change the composition form of the input text and let the user to (de)compose where he needs a fixed composition form, so that QString(wellformed_unicode_text).toUnicode() == wellformed_unicode_text.
