How to write an i-breve (an i with a breve accent, but without the dot)

Question

If I try something like \u{i}, I get both the breve and the dot. How can I get it without the dot?

Welcome to TeX.sx! A tip: You can use backticks ``` to mark your inline code as I did in my edit. — doncherry, Jul 03 '12 at 00:51
this is a pretty basic question. i suggest reading a good introduction. "the not so short introduction to LaTeX2e" (texdoc lshort if you're using a system based on tex live) is a good place to start. this topic is addressed on p.24 in the section "accents and special characters". — barbara beeton, Jul 03 '12 at 13:16
How come \u{i} doesn't do what you want, but \'i seems to work fine? (For me at least). — Jordan Mitchell Barrett, Jan 01 '21 at 07:07

The dotless i is \i; so you would want \u{\i}. (A dotless j is, likewise, \j).

On math mode one should use \imath and \jmath. – Waldir Leoncio Mar 17 '16 at 13:33
@WaldirLeoncio but in math it would be \breve not \u – David Carlisle Apr 20 '17 at 10:31

Use math simbols:

\breve{\imath}

Or

\breve{\jmath}

\breve is the accent and \imath / \jmath are i / j without the upper dot

In the modern toolchain, with LuaLaTeX or XeLaTeX, load fontspec and all of the following will work, along with several others.

\documentclass{article}
\tracinglostchars=2
\usepackage{amsmath}
\usepackage{fontspec}
\newcommand\mibreve{\textnormal{ĭ}}
\newcommand\mitibreve{\textnormal{\itshape ĭ}}
\begin{document}
ĭ \u{i} ^^^^012d \symbol{"012D} {\char"012D} ( \mibreve, \mitibreve )
\end{document}

In a legacy 8-bit engine, you can still use the precomposed character ĭ (U+012D), but not the combining accent ◌̆. You can define \u{i} to give you \u{\i} instead with \DeclareTextCompositeCommand.

\documentclass{article}
\tracinglostchars=2
\usepackage{amsmath}
\pagestyle{empty}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc} % The default since 2018
\DeclareTextCompositeCommand{\u}{T1}{i}{\u\i}
\newcommand\mibreve{\textnormal{ĭ}}
\newcommand\mitibreve{\textnormal{\itshape ĭ}}
\begin{document}
ĭ \u{i} ( \mibreve, \mitibreve )
\end{document}

This would also work in OT1.
