How do I generate this u with acute accent and under horn?

Question

Below is the photo of the word that uses this letter. The language is Jemez, fwiw.

Is there such a unicode character? What is the name of that "thing" under the letter? How do I obtain it in latex?

Answer 1

It could be a "u" with acute accent and ogonek. It doesn't seem to exist in unicode, but it can be obtained by stacking a u with ogonek (U+0173) and an acute accent.

If you use a unicode-based engine, you can directly use the symbol "ų́" in the code.

\documentclass{article}
\begin{document}
ų́
\end{document}

If you use pdfLaTeX, you can use \k for the ogonek and \' for the acute accent.

\documentclass{article}
\usepackage[T1]{fontenc}
\begin{document}
\k{\'u}
\end{document}

Answer 2

What is the name of that "thing" under the letter?

This subscript curl looks like an ogonek. It may also be a coma bellow or single quotation mark bellow, or even a cedilla.

Is there such a unicode character?

Per se no. No such precomposed character, but Unicode know and allow all diacritical marks via combining characters.

How do I obtain it in latex?

If it's ogonek, as I think,

• with LaTeX2e alone and T1 encoding, you can use \k{u} or \textogonekcentered{u}
• with tipa package and T3 encoding, you can use \textpolhook{u} or something like (not sure but I think it's sampa...) \textipa{u_=}

Of course, to combine with the apex too. e.g. \k{\'u}.
