I got curious about font subsetting, which I usually don't do, because I usually don't embed fonts in the first place.

I got the following error(s):

Spoiler:

Status: failed

Using external Python interpreter.

This usually isn't a problem, but if you run this code on another system, or in a different virtual environment, it may use a different parser and behave differently.

To get rid of this warning, change this:

 BeautifulSoup([your markup])

to this:

 BeautifulSoup([your markup], "lxml")

  markup_type=markup_type))

I'm running linux, Kubuntu 16.04.3, Sigil 0.9.9 compiled from source, Qt 5.6.1. I believe I have all the needed python modules installed.

Running pyftsubset from the command line, using the above character string supplied in a file, runs successfully.

I must be missing something. Probably something obvious.
