I want to write the Greek letter theta with two dots over it in text mode, but I haven't gotten it to work yet.

I have both these packages:

\usepackage{amsmath} 
\usepackage{textgreek}

and I have used \straighttheta when writing theta without two dots.

Thank you!

  • Welcome. You can use \usepackage{upgreek} for straight theta and for two dots above \ddot. So the final comand should be $\ddot \uptheta$. Unfortunately, you need the matmoade $$ for the dots – Excelsior May 4 at 18:19

You can use alphabeta:

\documentclass{article}
\usepackage{alphabeta}

\begin{document}

\accdialytika{\texttheta}

\end{document}

Here there is an old answer Adding a dot over greek letter in text mode of @Steven B. Segletes that I have slightly changed.

\documentclass[a4paper,12pt]{article}
\usepackage{textgreek,stackengine}
\newcommand\textdot[1]{\stackon[1pt]{\csname text#1\endcsname}{.}}
\newcommand\textdots[1]{\stackon[1pt]{\csname text#1\endcsname}{..}}
\begin{document}
\textdot{theta} and \textdots{theta}

\end{document}

The dots can be in the font itself, too.

More than a hundred diacritical marks, able to combine automatically with the preceding character, are available when using a suitable Unicode True Type/Open Type font, including the double dot U+0308 COMBINING DIAERESIS (e.g., here on an o: ö ). As much as the font renderer, like a browser window, can handle it, they stack, too: i̧̤̥̦̪̫̅̆̇̈̉.

Requires fontspec or unicode-math package, and compilation with xelatex or lualatex.

\noindent θ + a combining diacritical mark

\noindent \verb|θ^^^^0308| $\mapsto$ θ^^^^0308

\bigskip
It would be handy to have a set of commands with (relatively) short-names to access these combining diacritical marks rather than having to type in the codepoints or the mark directly, such that, for example, \colorbox{blue!5}{\color{blue}\ttfamily a\textbackslash cdmacute} produces {\color{blue}a\cdmacute}, \colorbox{blue!5}{\color{blue}\ttfamily a\textbackslash cdmdotb} produces {\color{blue}a\cdmdotb}, and so on.
