subscript text is converted to strikethrough

[zkamvar]

I noticed this in ropensci/tinkr#99, but subscript text (at least with pandoc markdown) is converted to strikethrough (with two ~) on roundtrip between markdown -> XML -> markdown

commonmark::markdown_commonmark("H~2~O", extensions = TRUE)
#> [1] "H~~2~~O\n"

This looks like a bug in cmark, can you report in in https://github.com/github/cmark-gfm ?

It appears that this is a feature, not a bug 😞: github/cmark-gfm#71 (comment)

Ok so there is nothing i can do :/

It turns out there was a fix for this and that was to set the CMARK_OPT_STRIKETHROUGH_DOUBLE_TILDE option. I've opened #31 to address it.
