Hi Antonio,
FYI, the Microsoft NTFS filesystem only stores files names in UTF-16LE (BMP).
It does not store it as anything else. All other code pages are seamlessly and
transparently translated back and forth by Windows on-the-fly. This is true
even for the UTF-8 code page that Windows (partially) supports.
Regards,
Andrew

Ok. That's important.
The file system stores the names in some encoding, which can be Unicode for
instance. But when the Lua interpreter receives that string some conversion is
required, since the string is necessary a "char*" in main (remember that Lua
is implemented in C). The converted string is then passed to the fopen
function inside IM and everything works fine.
But if you write the same string inside a Lua script, that conversion does
not occurs. It will depend on how the text is encoded in the script. The
difference between the encoded string in the script and the converted string
received in the command line is the key issue here. So which encode we should
use in the Lua script so it will work too?
Before we answer that I would like you to do another test please, with the
same file:
require"iuplua"
require"iupluaim"
local filename = iup.GetFile("*.*")
print (filename)
ih = iup.LoadImage(filename)
if (not ih) then
print "Failed"
else
print "OK"
end
I attached the script also.
Thanks,
Scuri

Test works fine in cmd.exe with my path and file name.
And I'm confused how to use these path and file name in code, such as embed
Filepath to loadimage in Lua.
Thanks
Sorry, that was a typo.
We can continue here. Once we solved I will post it there. Sometimes is less
noise.
The idea was to test using "arg" in the Lua interpreter. For instance:
D:\tecgraf\iup\bin\Win32\Lua53>lua53 d:\Downloads\loadimage.lua
d:\downloads\blacksad1.jpg
d:\downloads\blacksad1.jpg
OK
Best,

Sorry, I don't quite get it.
1. I change 'require"iupim"' to 'require"iupluaim"', otherwise I'd get "error
loading module 'iupim' from file" .. "Can't find specify program".
2. After change it, code could be ran.
3. I didn't change or update anything other than iup-3.25. Should I ?
Problem still exist when 'file name and path contain multi-bytes characters',
get "Failed" from print.
And change a path and file would get "OK" as expected.
BTW, I send this mail directly to your gmail, should I send it to iup-user
mail list?
require"iup"
require"iupim"
print [[....]]
ih = iup.LoadImage[[....]]
if (not ih) then
print "Failed"
else
print "OK"
end
