Ah ok. That's why the MSDN sample code for SCardListReaders() uses
"printf("Reader: %S\n", pReader );" (note the capital S in %S).
So we have an API difference between pcsc-lite and MS PC/SC :-(

pcsc-lite can use UTF-8 since the reader name is transparent for
pcs-lite. Just put whatever reader name you want /etc/reader.conf of
Info.plist.
I don't know why MS chose to use UTF-16 instead of UTF-8. UTF-8 is
backward compatible with ASCII so (very) easy to migrate to.
