# backslash, respectively." <https://specifications.freedesktop.org/desktop-entry-spec/
# desktop-entry-spec-1.1.html#basic-format> says "A file is interpreted as a series of lines
# that are separated by linefeed characters", so it is apparently necessary to escape at least
# linefeed and backslash characters. It is unclear why that spec talks about "linefeed" in
# one place and about "newline" ("\n") and "carriage return" ("\r") in another, and how they are
# supposed to relate, so just escape any U+000A LINE FEED as "\n" and any U+000D CARRIAGE RETURN
# as "\r"; it is unclear exactly which occurrences of U+0020 SPACE and U+0009 CHARACTER
# TABULATION would need to be escaped, so they are mostly left unescaped, for readability:

# U+0020 SPACE or any kind of white space, in which case at least a leading U+0009 CHARACTER
# TABULATION should similarly be escaped as "\t"; also, it is unclear whether such
