I forgot to attach the example files. Thanks, Paul

And for Cambria Math: Missing character: There is no (U+02B9) in font cambria! Missing character: There is no (U+02B9) in font cambria! Which is not surprising, since it is the wrong glyph to use (it is a phonetic modifier, not a math symbol). The right one is indeed U+2032 PRIME, but there the odd thing is that all the math fonts (including Cambria Math) have a big glyph in that slot that lives on the baseline (instead of a superscript one). So, you need f^′(x) = 1 as luigi showed. Best wishes, Taco

Not really, the glyph in U+2032 is raised and scaled down in most math fonts with the exception of Asana Math and LM Math (the large, baseline form is mapped through ssty feature in other fonts), I consider this a font bug or inherited TeX legacy. Regards, Khaled -- Khaled Hosny Egyptian Arab

indeed. so I will make a virtual glyph of it Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

\prime should superscripted, ^\prime (as it can be used in subscript as well), and apparently the same goes for U+2032. U+02B9 is not a math symbol. ASCII apostrophe is, more or less, short of ^\prime in math mode, so f'(x) should do just fine. Regards, Khaled -- Khaled Hosny Egyptian Arab
