Maybe so, but it does debunk the statement "does not happen too often".

OK, so zero is maybe incorrect. Let change it to 1 conversion (the
file contents only, seeing that just about nobody stores files in
UTF-16 encoding). Now compare 1 conversion to the multiple conversions
under Linux if the RTL is only UTF-16 based.

And as you so clearly stated in a prior message, it depends on what
your application does. Some programs will be heavily penalised by so
many conversions.
