The only previous mention I could find of this was over a decade ago and I hope ancient history. Running 5.32 on win10 and I have the unfortunate situation of having a bunch of files with Unicode in the file names. This, apparently, doesn't bother win10 but I'd like to get rid of the garbage and Perl can't seem to access them, quite. I do an opendir/readdir to get the file name. When I look at the file with windows I see things like 
___________________________ ✈️ ✈️ ✈&#6

but when I look at the file name in Perl I see 
___________________________ ?? ?? ??

and if i try to access the file from Perl I get an "can't find the file" and i even tried doing it via windows with  system "ren \'$UNIFILE\' $reasonablename" and windows can't see the file {and of course trying "-f $UNIFILE" in perl tells me that it isn't there}.

I've always been hopelessly confused in dealing with Unicode in perl but from what I have read, it seems that it is all supposed to "just work"... but apparently not for file names and accessing the file system.
