Text in custom font has wrong encode is svg

[linsui]

The tex file is

\documentclass[margin=3pt,dvisvgm]{standalone}

\usepackage{fontspec}

\begin{document}
\newfontfamily\arial{Arial}
\arial abcde
\end{document}

I generate the svg with

xelatex -no-pdf test
dvisvgm --zoom=-1 --exact --font-format=woff test.xdv

The result looks well, however if I copy the text from the svg I get ΤΥΦΧΨ. Pdf generated by xelatex is correct.

The issue is caused by an ambiguity in the mapping table that maps glyph indices to code points. It's easy to fix. I'm going to commit a patch shortly.

Thanks!
