I am looking for a way to encode this symbol:
This is the natural check mark for a left-handed person, as this is what happens when we apply an outward flick of the wrist to a pen. However, all the checkmarks I have found for LaTeX are right-handed.

Besides what has been said in this post. You can also define a new "bigcdot" operator using scalerel package, for example:
\documentclass{article}
\usepackage{amsmath,scalerel}
\DeclareMathOperator*{\Bigcdot}{\scalerel*{\cdot}{\bigodot}}
\begin{document}
\[\Bigcdot_{i=1}^\infty A_i=A_1+A_2+\cdots\]
\end{document}
gives you:
EDIT:
I considered some alternative solutions so I will post them here.
As one can see, a problem with the scalerel solution is that it stretch the \cdot too wide such that the symbol become less appeal (at least to me). So how do we get a smaller dot with bigger "size"? For instance, let's say we want to have the dot in \bigodot (we can use \boldsymbol{\cdot} for the dot only) without the circle, how do we do it?
Well, there are at least two ways: first, we want to declare this new symbol as a math operator, such that superscript and subscript will go directly above and below it, then we either enclose the bold cdot with a box of total height of \bigodot, or we insert a invisible character of the size of \bigodot after the bold cdot, as illustrate by the code (both do not need any package other than amsmath):
\newsavebox\dotbox
\sbox{\dotbox}{\(\displaystyle\bigodot\)}
\DeclareMathOperator*{\bigcdot}{\raisebox{0pt}[\ht\dotbox][\dp\dotbox]{\(\boldsymbol{\cdot}\)}}
and
\newsavebox\dotbox
\sbox{\dotbox}{\(\displaystyle\bigodot\)}
\newlength{\dotheight}
\setlength{\dotheight}{\ht\dotbox}
\addtolength\dotheight{\dp\dotbox}
\DeclareMathOperator*{\bigcdot}{\boldsymbol{\cdot}\rule[-\dp\dotbox]{0pt}{\dotheight}}
That said, we can also redefine other "small" symbol, such as \bullet and \|, in similar ways. In the end, let's compare the results:
\[
\Bigcdot_{i=1}^\infty A_i=\bigccdot_{i=1}^\infty A_i=\bigcdot_{i=1}^\infty A_i=\bigodot_{i=1}^\infty A_i=\sum_{i=1}^\infty A_i
\]
The "Mathematical Script Small R" is just a Unicode character, so if you can enter it in your editor, and you have a font that includes a suitable representation, then it's as simple as this:
\documentclass[a4paper]{article}
\usepackage{fontspec}
\setmainfont{STIXGeneral}
\begin{document}
small r: 𝓇 there.
\end{document}
I'm using MacVim and xelatex with TexLive 2013 here and I get this
On the Mac you can get the symbol from the character viewer. This is the information it gives about it.
𝓇
MATHEMATICAL SCRIPT SMALL R
Unicode: U+1D4C7 (U+D835 U+DCC7), UTF-8: F0 9D 93 87
And if entering the character from the viewer is too laborious you can always define a little macro for it:
\def\arr{\hbox{𝓇}}
(This feels vaguely like something for http://www.talklikeapirate.com/)
