9. The mathcode thing has to be used with care under Unicode engines Unfortunately the luatexUmathcode macro is helpless update I have since been told by TH that the next LuaLaTeX release will change this as it is not possible to know if it will return a legacy mathcode or a Unicode mathcode On the other hand the much saner XeTeXmathcodenum always return a Unicode mathcode 1 15e Oct 22 2012 I add the necessary things to also subdue the mathbf mathit mathsf and mathtt macros previous version only took care of the symbol alphabets mathnormal and mathrm update 1 15f does that in a completely different and much simpler way Notice that the package defines a mathnormalbold macro but it will not be subdued in the normal and bold math versions 1 15f Oct 23 2012 The previous version of the code queried the math family of a respectively 1 to guess and then extract the fonts to be reassigned to mtletterfont and mtoperatorfont which is done at the end of this sty file The present code simply directly uses letters and operators so mathastext could not subdue itself if it was somehow cloned but obtains indeed the corresponding font specifications in normal and bold in a cleaner manner But it is so much shorter and avoids the LualATEX problem with luatexUmathcode Anyhow for example the euler package puts the digits in the letters math family so the previous method was also error prone In fact there is no way to do this su

17. As is usual with ATEX one can limit the scope to the inside of a group or also switch back to the main set up through issuing Mathastextver sion normal When Mathastext is used in the preamble it records the current font defaults and except for the normal and bold versions under the subdued regime sets up the math font to be used in that version to be the text font as found in familydefault But it is still possible for a mathastext declared math version to have distinct fonts for text and math 1 in the body of the TEX source an optional argument the name of a mathastext declared math version to MTversion is allowed and for exam ple we used in the source of this document MTversion newcent helvet meaning New Century Schoolbook for the text and Helvetica for the math 2 there are preamble only commands MTencoding MTfamily MTseries MTshape MTlettershape which tell mathastext what to do for math only in each math version declared afterwards independently of the text fonts In the body of the document the ATEX command mathversion version_name will change only the fonts used in math mode It is recommended to use instead the package command mathastextversion or its synonyms MTversion Mathas textversion MTVersion with a mandatory argument version_name It e checks in case the subdued option was specified whether the asked for math version is normal or bold and adapts the following to that c
18. Lual TEX it is recommended to use the fontspec package Else some of the encoding dependent things done by mathastext like using the en dash character to get a minus sign in math mode will not be put in place Furthermore it is necessary to load fontspec with its no math option and this must happen before loading mathastext Use fontspec with its no math option and load it prior to mathastext The amsmath package if used must be loaded prior to mathastext A little piece of the functionality of mathastext is less fully realized under the LualATEX engine than it is with KHIRK This is a temporary situation as the needed feature of Lual4TfX has been implemented in its latest development release I will update mathastext when these binaries will have reached the distribution stage I already mentioned in the section 29 the fact that the italic corrections were not available for OpenType fonts under the XqIfX engine and only partially available for the LualATEX engine with the result that the spacings in math mode when using for the letters an upright text font will be less satisfying than with the standard pdfetex engine the OpenType fonts not being usable with the latter engine this is not a criterion of choice anyhow To specify math versions using unicode fonts use the fontspec setmainfont command with arbitrary optional features This command can be issued before loading mathastext or after and then will be follow
