In principle, the user doesn't have to do so. UTF-8 itself is agnostic to the
endianness of the system.

The endian issue only comes up in the source code. To solve this, we have to
handle UTF-8 when reading the source code. libcpp, which we use for the input,
handles multiple encodings. We should use find out how to use this - and use it
for 4_'strings'.
