I would like to use a specific diacritic: The combining macron-grave. The USV code is U+1DC6, and an example of the diacritic is shown below:

enter image description here

I've searched through all the symbol guides I can find, but to no avail. The tipa package has \textgravemid{}, which is the right idea, but the grave and the macron are the opposite way round to what I need.

Does anyone know of a symbol like it? Or of a way of combining the macron and the grave so that they're not stacked, but one following the other? Or, failing that, whether I can define a new symbol?

  • Welcome to TeX.SX! You should tell us a bit about the usage of this symbol. Which language is it used in? What is the context (math, text), are you using PDFLaTeX or Xe- LuaLaTeX? It would be perfect if you include an MWE which shows a minimal version of your document if you define some languages, fonts or alike. – LaRiFaRi Mar 16 '15 at 10:47

Using lualatex or xelatex you can use the \accent primitive (giving the accent before the base) or simply use the unicode combining character mechanisms referring to the character using ^^^^ or just typing directly:

enter image description here

\documentclass{scrartcl}
\usepackage{fontspec}
\setmainfont{Times New Roman}
\begin{document}

\accent"1DC6 u

u^^^^1dc6

u᷆
\end{document}

The last line there is

  U+0075 LATIN SMALL LETTER U
  U+1dc6 COMBINING MACRON-GRAVE

Make your own. The dimensions may need changing based on the font being used. The [-1ex] controls the overset gap, the \kern-.27ex controls the relative horizontal placement of the two overset glyphs, while the {-.94ex} controls the relative vertical placement of the two overset glyphs. Using the scalable ex rather than pt allows the macro to work at different font scales.

By setting \useanchorwidth to the {T}rue setting, the width of the overset does not affect the spacing of the base letters (shown in the MWE on a narrow i to demonstrate).

\documentclass[12pt]{arlticle}
\usepackage{stackengine}
\newcommand\mg[1]{\def\useanchorwidth{T}%
  \stackon[-1ex]{#1}{-\kern-.27ex\raisebox{-.94ex}{\`{}}}}
\begin{document}
\mg x \mg X

\Huge \mg x \mg X

Small w\mg idth
\end{document}

That diacritic seems to be used in some of the ›Bantu‹ languages: http://fr.wikipedia.org/wiki/U%E1%B7%86.

The following works fine for me (using LuaLaTeX):

\documentclass{scrartcl}
\usepackage{fontspec}
\setmainfont{Times New Roman}
\begin{document}
\accent\string"1DC6 u
\end{document}

You may want to have a look at the newunicodechar package. It may help you be able to type u᷆ directly:

\newunicodechar{u᷆}{\accent\string"1DC6 u}
