Yes, it does -- where that's TRT.  For example, when displaying them.
And sometimes this is a user option; e.g., see character-folding in
Isearch.

IMO, Guile should provide the facilities to handle them the same, and
leave for the higher-level code to use whatever is suitable.

In any case, this is unrelated to how strings are implemented, because
the basic level of string implementation _must_ support binary,
character by character (and byte by byte) comparison.  Otherwise, you
won't be able to compare file names equal, for example, at least on
Unix and Windows (macOS is another matter).
