I just wanted to make something clear.

The escaping or encoding of special characters is not related to ASCII
or Unicode.
Some characters are escaped (or encoded) because they have a special
meaning for the syntax used in the file.

For instance, you can find on Wikipedia that ':' can sometimes be used
as a '=' character.
So if it were not encoded you could end up with:

    var:foo=bar

which can be interpreted as either "var" = "foo=bar" or "var:foo" = "bar".
