Dot below letter [duplicate]

Question

TeX accents do not seem to work with fontspec and xe/lua/latex

Very frequently I need to write letters with dots below (like ḥ or ṭ) for transliteration. It's ok when the font I'm using comes with the character, but I can't use that character with other fonts.

It used to work with xelatex and xunicode package, I'd just use \d{t}, for example, but that doesn't seem to be the case anymore, it just works if the font has that particular character.

Is there a way to "force" a dot below a letter in any font?

Here is the basic preamble I've been using:

\documentclass{article}
\usepackage{fontspec}
\usepackage{xunicode}
\setmainfont{Minion Pro}

EDIT:

OK, I found the simplest solution myself, I just changed the preamble to (all the rest being equal):

\documentclass{article}
\usepackage{xunicode,xltxtra}

So now I can put that \d{} (dot below) on any character, any font.

I hope this helps people with the same issue.

Answer 1

You can use the stackrel package to place things above or below text. E.g.:

\documentclass{article}
\usepackage{stackrel}
\begin{document}
    $\stackrel[\textrm{.}]{}{\textrm{k}}$
\end{document}

I have used a period here, but you could probably substitute another character to serve as the dot, such as "˙".

Another option might be to change the font when placing the dot underneath. Look in the character map under "Combining diacritical marks". These are characters which essentially stacked in the same place as any character placed before. You may be able to use one font for the letter, then use another font for the diacritical mark.

Answer 2

\documentclass{article}
\usepackage{fontspec}
\usepackage{xunicode}
\setmainfont{Minion Pro}
\begin{document}

\Huge \d{o}

\end{document}
