Vector command with harpoon arrow over all characters

[full wolf]

Currently, the command \newcommand{\vek}{\overset{\rightharpoonup}} creates a harpoon styled arrow over one letter, such as a. But if I add more, the arrow doesn't appear to change in size, as if there was only one character and not more. See the following example:

\documentclass{standalone}
\usepackage{amsmath}

\newcommand{\vek}{\overset{\rightharpoonup}}

\begin{document}

$\vek{a}$
$\vek{AB}$

\end{document}

Basically, I want an arrow that spans the length of all given characters, not only one. As a bounus, I would like the arrow to be slightly lower than it is at the moment.

I assume I again didn't need to use curly brackets like I did before with the other command #1090265695520038912 message

pdfMsym – PDF Math Symbols — various drawn mathematical symbols

This package defines a handful of mathematical symbols many of which are implemented via PDF’s builtin drawing utility. It is intended for use with pdfTeX and LuaTeX and is supported by XeTeX to a lesser extent. Among the symbols it defines are some variants of commonly used ones, as well as more obscure symbols which cannot be as easily found in other TeX or LaTeX packages.

pdfMsym provides \overrightharp

Thanks for the notice plante ❤️

Here you would if you want your input to be more than one token/character, since \overset does take the following group as a parameter

About time tbh

Very cool you got a Very Active role :O

So there's no nice solution using only \newcommand and amsmath?

omg you made the package?

seemed weird the dates were recent

Some alternative solutions:
Using amsmath: https://tex.stackexchange.com/questions/530761/special-vector-over-text-half-head-of-the-arrow-vertically-compact
Using the harpoon package: https://tex.stackexchange.com/questions/344778/latex-vector-notation-arrow

Yeah hence the excitement, as I could recommend my package to someone unironically
