Fontforge: How to "remove overlaps" making work - svg

Question

I create an arrow in TikZ and convert it to svg (pdf2svg file.pdf file.svg).
Then I import my output.svg into FontForge and choose there Element --> Overlap --> remove.
Finally I put the character \symbol{65} into a tex-document, but I have still these 'overlaps' in form from white space inside the sign.
Could somebody help me to create the sign correctly?
% arara: lualatex
\documentclass[varwidth, margin=15mm]{standalone}
\usepackage{tikz}
\usepackage{fontspec}
\newfontfamily{\myfont}[Scale=1]{myfont.ttf}
\begin{document}
\textbf{For output and svg-conversion}
\begin{tikzpicture}[line width=5mm]
\draw[-stealth] (0,0) -- (5,0);
\end{tikzpicture}
\textbf{Input from myfont.ttf}
\myfont\Huge\symbol{65}
\end{document}

output.svg
myfont.ttf (only 1 character at No. 65)

If the number of arrows is not too big, you can post-process the svg file with inkscape
select all and ungroup a couple of times
now use Stroke to Path option
and finally union all the shapes
This will result in an svg file like this:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
