Image converting does not work if path does contain non-English letters

[enthusiast]

If file "filelist.txt" contains paths with letters other than English, such as Chinese or Arabic, like "D:\files\习近平.jpg", the convertation of images, located on these paths, will not work.

XnConvert has a similar problem; such images are not loaded into preview window and do not participate in convertation.

XnViewMP handles such paths normally and converting happens!

Is it possible to add support for such letters in Nconvert and XnConvert as well?

Nconvert: 7.136
XnConvert: 1.98
System: Windows 10 x64, en.

Pierre was developing an NConvert version with better Unicode support earlier in the year, but unfortunately the link to the test version that he produced, which was reported to work for Korean characters, is no longer available...

Maybe in the next update?

you can try the unicode beta version

I tried beta version, but I get error again.

File filelist.txt:

Code: Select all

D:\file 1.png
D:\file روز.png

Command:

Code: Select all

nconvert.exe -l filelist.txt -q 90 -D -out webp

Result:

Code: Select all

Conversion of D:\file 1.png into D:\file 1.webp OK
  Error: Can't open file (D:\file روز.png)

If you don't use a filelist and run something like this:

Code: Select all

nconvert.exe -q 90 -D -out webp روز.png

?

In this case, conversion works, although it outputs question marks instead of file name in Terminal:

Code: Select all

>nconvert.exe -out webp روز.png

Conversion of ???.png into ???.webp OK

In file system the file is written with a normal name: روز.webp

The fact that the modified code runs suggests that there was a problem with the file list coding, doesn't it?

Maybe Pierre can help with the above 'question marks' issue...

Edit: Can you upload a small test file?

[enthusiast]

As far as I know, encoding of my filelist.txt is UTF-8.
I've attached my example as an archive. There are three files: abc.png, روز.png, FL.txt. I can upload them separately if archives are not allowed here.
My command when I'm inside a folder:

Code: Select all

>nconvert.exe -l FL.txt -out webp
Conversion of abc.png into abc.webp OK
  Error: Can't open file (روز.png)

But when the file is run directly conversion works, although it outputs question marks instead of file name in Terminal:

Code: Select all

>nconvert.exe -out webp روز.png

Conversion of ???.png into ???.webp OK

In file system the file is written with a normal name: روز.webp

I tried beta version, but I get error again.

File filelist.txt:

Code: Select all

D:\file 1.png
D:\file روز.png

could you send me the filelist.txt file?

It is in the ZIP, isn't it, or do you need something else?

Please try this version

[enthusiast]

Please try this version

It's working now, thank you!

Code: Select all

>nconvert.exe -l FL.txt -out webp
Conversion of abc.png into abc.webp OK
Conversion of ???.png into ???.webp OK
Conversion of def.png into def.webp OK

The file is saved with the name روز.webp, so the question marks in the console don't bother me.

Hopefully this feature will be included in the next versions of XnConvert and Nconvert...

I know that this is beta version but I found out that it can't compress/process (can save png to avif but can't avif to avif) avif images ("my_error_exit...<Not a JPEG file: starts with 0x00 0x00> Error: Don't know how to read this picture" if "-in avif" command used shows only this message "Error: Don't know how to read this picture") but previous version (7.136) works fine. Also another problem that to make it work for/to jpeg-xl compression latest libJPEGXL.dll from XnView MP v1.53 needed or this don't works (in console/cmd shows that all OK but for real file is not creating) and in v7.136 (non Unicode) saving any images to jpeg-xl not working at all while in v7.121 it worked fine.
Commands used for avif:
nconvert.exe -v -32bits -out avif -o 2.avif" -avif_speed 8 -avif_quant_color 0 25 30 -avif_quant_alpha 0 25 30 -in avif "1.avif"
nconvert.exe -out avif -o "2.avif" "1.avif"
P.S. All needed plugins placed in plugins folder. Probably bug related to that problem viewtopic.php?f=57&t=43732 (and Unicode version don't have it fixed).
