This is a very good idea to determine whether or not the data is text,
but if it is you still need to handle text encoding so it's more of a
pre-step to the other options.

Projects will very frequently have mixed encodings, especially if they
are internationalized (e.g. generally every .po file will be in a
different encoding that has nothing to do with the user's locale).
Also right now many projects will be in a transitioning phase from a
native encoding to UTF-8, or have any other number of valid reasons
for working with multiple encodings.
