The apostrophe is essentially equivalent to ^{\prime}, which is the reason for the output you get from ^{\dagger''}. It's a very handy shorthand in most cases, compare f'(x) with f^{\prime}(x). In your case you don't want a second level superscript. Solution: use \prime. \documentclass{article} \usepackage{amsmath} \begin{document} \[ \hat{c}_{\omega l}^{...

You can always build your own. That way you can change details, if needed. \documentclass{article} \usepackage{tikz} \usepackage{scalerel} \newcommand\TalkingHead[1][]{\scalerel*{\begin{tikzpicture}[#1] \draw[xscale=-1,line width=pi*1mm] (-1,-4) to[out=50,in=-90,looseness=1.4] (-1,-3) to[out=-160,in=0] (-2,-3.2) to[out=180,in=-120] (-2.7,-2) to[out=120,...

I guess, you just made a typo (capital-X). The following code works for me. \documentclass[a6paper,landscape]{memoir} \begin{document} I love \LaTeX.\footnote{\LaTeX\ code has been taken from this source.} I also love \TeX.\footnote{\LaTeX{} code has been taken from this source.} \end{document} Compiled with pdfTeX: To clarify: I posted an answer ...

Raise the asterisk by 1ex minus the height. \documentclass{article} \usepackage{fontspec} \setmainfont{Alegreya} \newcommand{\gs}{\raisebox{\dimexpr1ex-\height}{*}} \begin{document} \makebox[0pt][l]{\vrule height\dimexpr1ex+0.05pt depth -\dimexpr1ex-0.05pt width 3cm}% \makebox[0pt][l]{\vrule height 0.05pt depth 0.05pt width 3cm}% x Autor\gs in \end{...

The approach here is a little complicated. Why? need to get the symbol centered between the two glyphs, even if the two glyphs are of different widths Need to make work across math styles. Need to make the accent glyph leave the spacing unchanged in the underlying glyphs. Need to auto-adjust vertical placement depending on height of underlying glyphs. The ...

There is also a specific symbol \leqslantdot with MnSymbol package, or fdsymbol. Edit: We observe that the \leqslantdot with MnSymbol not changes the CM fonts. \documentclass[12pt]{article} \usepackage{amsmath} \usepackage{MnSymbol} \begin{document} $f(a,b)\leqslantdot g(b,a)$ \end{document} While if you use fdsymbol, you have not an exact dot but it is ...

You can use the e argument specifier of xparse to scan and see whether subscripts or superscripts come along. If they do, add \, to superscripts and \! to subscripts. This happens by adding \fixlimits at the end of the working of \int. You may want to do similarly to other integral types, with a similar \xapptocmd line for each. \documentclass{article} \...
