Typst writer does not escape double forward slashes (//)

[tsamsonov]

Explain the problem.
According to Typst syntax, double forward slashes are interpreted as comments. When the source text contains this pattern, the PDF resulting from Typst rendering is missing the remainder of the paragraph. Example is below.

Input markdown:

**Samsonov T.E.** Shape-Adaptive Geometric Simplification of Heterogeneous Line Datasets / T. E. Samsonov, O. P. Yakimova // International Journal of Geographical Information Science. — 2017. — Vol. 31. — № 8. — pp. 1485-1520.

Output typst:

#strong[Samsonov T.E.] Shape-Adaptive Geometric Simplification of Heterogeneous Line Datasets / T. E. Samsonov, O. P. Yakimova // International Journal of Geographical Information Science. — 2017. — Vol. 31. — № 8. — pp. 1485-1520.

Compiling Typst to PDF gives:

When applying this Lua filter:

return {
  {
    Str = function (elem)
      if elem.text == "//" then
        return pandoc.RawInline('typst', '\\/\\/')
      else
        return elem
      end
    end,
  }
}

Output Typst is

#strong[Samsonov T.E.] Shape-Adaptive Geometric Simplification of Heterogeneous Line Datasets / T. E. Samsonov, O. P. Yakimova \/\/ International Journal of Geographical Information Science. – 2017. – Т. 31. – № 8. – С. 1485-1520.

And the resulting PDF is okay:

Resume

Since // is not a comment in the input, it is expected that it remains so in the output. I suggest that Typst writer should escape double forward slashes in plain text.
