Hi Fabrice, Wolfgang gave the right answer, but I wanted to point out that it is better not to use \setupbodyfont in the middle of your document, as you did in the excerpt below: in this case it is better to use \switchtobodyfont[xits] or even better define the character you want before using it as in \define\CScript{\start\switchtobodyfont[xits] \m{\mathscript{C}} \stop} and then use that command as in: La droite \m{(AM)} est {\bf une sécante} à la courbe \CScript en \m{A}. Another solution is to define your own mixture of math fonts and text fonts. Best regards: OK

Hi Fabrice, I use Lucida OT fonts for all my documents, but since I prefer the script fonts from another font I have the following setups for my font: %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %% Some Font Definitions \definefallbackfamily[myfont][math][Asana Math] [range={uppercasescript,lowercasescript}] % lucida font \definefontfamily[myfont][serif][Lucida Bright OT] \definefontfamily[myfont][math][LucidaBrightMathOT] \definefontfamily[myfont][sans][LucidaSansOT] \definefontfamily[myfont][mono][LucidaSansTypewriterOT] \setupbodyfont[myfont,9pt] %% End of Font Definitions %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Then when I use for instance the command $\cal{C}$ the script font from Asana Math is used, instead of from Lucida OT. Best regards: OK

Hi Fabrice, The Lucida OT family is indeed not free (it costs 110 US dollars from TUG), but tha Asana Math is included in the distribution of ConTeXt, LuaMetaTeX and, I think, TeXLive. Best regards: Otared

Hi Aditya, Thanks for your hint: I didn't know that subtelty about Lucida OT (and I don't know how to set it up when using Lucida OT). That being said, actually what I would like to use is the kind of script font which is the attached document (those script fonts were widely used in higher mathematics textbooks in France). So when I use mkiv the result is the one I like and is attached to this message (test-scriptfonts-mkiv.pdf). However, thanks to your message I went to check, and noticed that lmtx does not give the same math script fonts, and I don't know what has changed between mkiv and lmtx regarding Asana Math, or the way in which fallback fonts are managed (please see the attached file test-scriptfonts-lmtx.pdf). Thanks for your help: Otared PS: this the the file test-scriptfonts.tex: %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %% Some Font Definitions \definefallbackfamily[myfont][math][Asana Math] [range={uppercasescript,lowercasescript}] % lucida font \definefontfamily[myfont][serif][Lucida Bright OT] \definefontfamily[myfont][math][LucidaBrightMathOT] \definefontfamily[myfont][sans][LucidaSansOT] \definefontfamily[myfont][mono][LucidaSansTypewriterOT] %\setupbodyfont[myfont,10pt] %% End of Font Definitions %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \starttext \startbuffer[test] Testing script fonts in maths \startformula x^2 + y^2 = z^2, \quad \sin(a)^2 + \cos(b)^2 = 1. \stopformula \startformula \cal{A}, \quad \cal{B}, \quad \cal{C}, \quad \cal{D}, \quad \cal{E}, \quad \cal{F}, \quad \cal{G}, \quad \cal{H}, \quad \cal{K}, \quad \cal{L}, \quad \cal{M}, \quad \cal{P}, \quad \cal{S}, \quad \cal{T} \stopformula \hairline \stopbuffer \switchtobodyfont[lucidaot] {\bf Lucida OT: } \getbuffer[test] \switchtobodyfont[myfont] {\bf Lucida OT with Asana Math: } \getbuffer[test] \stoptext

OT: Do you use this to get a less cursive script font?

Lucida (like many opentype math fonts) comes with two stylistic variants for script letters. The default is the cursive variant, but you can get the less cursive variant using ss04 stylistic set. See page 8 of https://tug.org/store/lucida/lucidaot.pdf
