Hello Jannik. Thanx. I know about ^\prime but this is the same as ^{'}. In this case is derivative symbol too higher - but emergency it can of course use. Use ^{'} or ^{\ prime} in LaTeX leads to equally poor results (too higher). Apparently to terms with the fact that it simply will not probably be better :-) ... In addition, I noticed that the broken line is too short (and it needs to be extended with spaces.). Thanks Jroslav Hajtmar Dne 5.2.2014 1:41, Jannik Voges napsal(a):

You should use ^\prime instead of '.

Hello ConTeXist.

I type some math now. When I use the symbol derivative in combination with symbols brackets, so the result does not look too good. Compared to the result in LaTeX output is almost unusable. It is possible to achieve a better result?

In addition, I noticed that the page numbering starts from number 2. Is it a bug or I wrong?

Thanx Jaroslav Hajtmar

Thanx Alan for the explanation. I tried use all of symbols ie U+2032 ′, U+0027 ' , U+2019 ’ and U+02BC ʼ. Visual results with using of U+2032 ′, U+0027 ' and U+02BC ʼ are the same as with symbol apostrophe ' (\prime) ... i.e. bad appearance (very low or very high with ^ symbol). Using of U+2019 ’ get error. Jaroslav Hajtmar Dne 5.2.2014 12:30, Alan BRASLAU napsal(a):

Windows (Word) is really "bad" in substituting the "right single quotation mark" for the ASCII (typewriter) apostrophe (U+0027). This is probably because some people in the unicode world decided that this be the "preferred" character to use for apostrophe (for some strange reason).
