Consider the following code : \font \greekfont = "Palatino Linotype" \greekfont U+1F7D : GREEK SMALL LETTER OMEGA WITH OXIA — ώ \par U+03CE : GREEK SMALL LETTER OMEGA WITH TONOS — ώ \par \end
The final (Greek) character on each of the two key lines is the character described by the preceding text. Yet after processing using XeTeX, the PDF output contains not (as expected) two different omegas bur instead two identical ones, both being U+1F7D : GREEK SMALL LETTER OMEGA WITH OXIA — ώ. Note that Unicode normalisation should not be taking place as I have deliberately left XeTeXinputnormalisation at its default value — \XeTeXinputnormalization ⟨Integer⟩ Specify whether XƎTEX is to perform normalisation on the input text and, if so, what type of normalisation to use. See http://unicode.org/reports/tr15/ for a description of Unicode normalisation. The ⟨Integer⟩ value can be: 0 (default) do not perform normalisation. 1 normalise to NFC form, using precomposed characters where possible instead [of] base characters with combining marks. 2 normalise to NFD form, using base characters with combining marks instead of precomposed characters.
