Newer and simpler solution Since v1.401 of newpxmath (released on October 2, 2019, now available in both MiKTeX and TeX Live), the package offers a new option fracspacing that “modifies fontdimens 8 and 11 of the symbol font to values more appropriate to the newpx fonts”. \documentclass{article} % New package option since 2019/10/02 ...

\colon and : are defined in fontmath.ltx using: \DeclareMathSymbol{\colon}{\mathpunct}{operators}{"3A} \DeclareMathSymbol{:}{\mathrel}{operators}{"3A} which makes \colon a punctuation and : a relation symbol, as you said yourself. You can swap the definitions: \DeclareMathSymbol{:}{\mathpunct}{operators}{"3A} \DeclareMathSymbol{\colon}{\mathrel}{...

The old-fashioned way, without relying on jalt or renderers: (1) Using lamed as an example, for a certain size and a certain font, typeset the glyph as a standalone pdf. (actual size) \documentclass[12pt]{standalone} \usepackage{fontspec} \setmainfont[Script=Hebrew]{FreeSerif}\usepackage{polyglossia} \setdefaultlanguage{english} \setotherlanguages{hebrew}...

\circ is a centred circle for degree you want ^{\circ} and you want\approx for U+2248. In general these days it might be easier to use pmml-new but with a TeX setup using luatex or xetex and unicode-math then the majority of math related unicode characters could be just sent straight through to TeX and would do the right thing automatically.

\textsc does not select two fonts it just selects one, however it is a font in which lowercase letters use the shapes usually assigned to uppercase. The relative heights as always for the relative heights of upper and lower case vary from font to font but are the choice of the font designer not something to set from TeX. Note that in most "true" caps-and-...

If you want to number a list (and reference the items) use enumerate and not itemize. I wouldn't make the number bold and sans serif. That simply looks bad. And I wouldn't suppress all the spacing - math needs more space, not less. \documentclass[a4paper,12pt]{article} \usepackage[T1]{fontenc} \usepackage{amsmath,amssymb} \usepackage{enumitem} \begin{...

Just remove \usepackage{lmodern} and \usepackage[T1]{fontenc}. \documentclass[9pt]{beamer} \mode<presentation> { \usetheme{JuanLesPins} \usefonttheme{serif} \usecolortheme{beaver} \setbeamercovered{invisible} \setbeamertemplate{blocks}[rounded][shadow=true] \setbeamertemplate{navigation symbols}{} \setbeamertemplate{footline}[...

It very much looks like the issue you've come across is a (bad) side-effect of using the polyglossia package, which seems to have a few issues when used with the brazil language option. Unless you absolutely must use the polyglossia package, an easy remedy consists of (a) getting rid of (or, at least, commenting out) the instructions \usepackage{...

Here is a working code: \documentclass[a4paper,12pt]{article} \usepackage[T1]{fontenc} \usepacke[utf8]{inputenc} \usepackage{amsmath,amssymb} \usepackage{enumitem} \begin{document} \begin{enumerate}[label=\sffamily\textbf{[\arabic*]}, noitemsep] \item $A^{\dagger}$ è un operatore \textbf{lineare}; \item $(A^{\dagger})^{\dagger} = A$; \item Se $A$ e $B$ ...

Since v0.8 embrac provides \embparen for cases like theorem-like environments. The error from the question with math mode cannot be reproduced… \documentclass{article} \usepackage{embrac}[2019-10-01] % v0.8 \newtheorem{theorem}{Theorem} \begin{document} \emph{$(x^2)$ not work!}% no error here \begin{theorem} Text \embparen{text} text \end{theorem} \...
