Hmm, it's just that Win32::GetLongPathName() returns the perl string I'd most expect in Win32-land. By "expect", I mean "jives with what I see in Windows Explorer".

Using Explorer, I created a file "snowman ☃" in a new folder "my_dir". That file was created by renaming an empty text file with "snowman " first, and then copy+pasting the snowman character. Then I ran the following:
#!perl use Win32; use File::Find; use Devel::Peek; my @paths; find sub { push @paths, ( $_, Win32::GetLongPathName($_), ) if /snow/i; }, "my_dir"; Dump $paths[0]; Dump $paths[1]; __END__ SV = PV(0x469c14) at 0x4f82b4 REFCNT = 1 FLAGS = (POK,pPOK) PV = 0x2621844 "SNOWMA~1.TXT"\0 CUR = 12 LEN = 16 SV = PV(0x469c2c) at 0x4f82f4 REFCNT = 1 FLAGS = (POK,pPOK,UTF8) PV = 0x262181c "snowman \342\230\203.txt"\0 [UTF8 "snowman \x{2603}. +txt"] CUR = 15 LEN = 16

The results tell me that the return string from Win32::GetLongPathName() is then fit for Unicode semantics in Perl. Nevermind the underlying filesystem encoding of NTFS (UTF-16LE ? I don't know), I can now treat the path as characters from then on.

Sure, long path names are opposite of short path names. What I'm saying is that Win32::GetLongPathName() is handy to get at the characters instead of octets given by File::Find.

    [erix]: then you might as well send that patch to the DBIC guys :)
    [Corion]: erix: Yeah, I just found that it has no documentation at all on how to circumvent/ eliminate "1+n SELECTs" by building a local hash... I guess I have to make ->has_many do the hash lookup instead of doing the SQL query. But as the problem ...
    [Corion]: ... has only manifested itself so far through the puzzled questions of other bystanders, I won't go deeper at this time. But the DBIx::Class documentation could well do with a document on how to make "it" (that is, ORMs in general) faster ;)
    [Corion]: I find that DBIx::Class, like most ORMs makes things easy until they become performance critical and then makes it horribly hard to change things because the design is highly inflexible if you don't already know about the problems of 1+n :-/
    [choroba]: that's why I don't like similar libraries. They pretend you don't have to learn SQL, but in the end, you have to learn how SQL plus to overcome their own limitations
    [Corion]: "Just write the proper SQL beforehand" is of course the appropriate solution, but if you did that, you wouldn't/couldn't use DBIx::Class either. At least not in an obvious (to me) way.
    choroba scratches a "how"
    [Corion]: choroba: Exactly... But maybe that's just because I'm old and grumpy ;)
