Hi,<br><br>In a previous email I commented that the integral symbols, when using the unicode font Cambria or Asana,<br>don&#39;t look ok. It has to do with the way e.g \iint, \iiint etc are constructed. Whether or<br>not the symbol is present in the unicode font, the tex macro \repeatintegral is used<br>
(fallback option). I don&#39;t want to use the Cambria or Asana font entirely, as the other math typesetting<br>doesn&#39;t look nice. Just for the missing symbols.<br><br>Found an earlier post (Thomas A. Schmitz titled symbols in luatex date 2008-01-02) where<br>
a solution was presented by Wolfgang Schuster. Basically I am using his solution<br>and came up with the following (only works ok in text mode). Also looked at definemathcharacter<br>but not sure how to make it work with unicode fonts (could not find any documentation,<br>
looked at the source files, but don&#39;t know what to fill in for the 6 parameters to definemathcharacter)<br><br>Question : what is the right way I can make this work (definemathcharacter, something else) ?<br>Question : some of these symbols are defined in char-def.lua but missing in math-vfu.lua. <br>
What is needed to make them active ? Can I do it myself and send a list of missing symbols with their unicode value ?<br><br>Thanks for the help.<br><br>% test of some math symbols<br>\starttypescript[serif][mathsymbols][name]<br>
