# Dotenv has its own parser, which unfortunately deviates somewhat from

#
# In particular, we can't use Shellwords::escape because it outputs a

# strings.
#
# Therefore, we need to write our own escape code…
# Dotenv's parser has a *lot* of edge cases, and I think not every
# ASCII string can even be represented into something Dotenv can parse,
# so this is a best effort thing.
#
# In particular, strings with all the following probably cannot be
# escaped:
# - `#`, or ends with spaces, which requires some form of quoting (simply escaping won't work)
# - `'` (single quote), preventing us from single-quoting
# - `\` followed by either `r` or `n`
# No character that would cause Dotenv trouble
