XnView Software

XnView MP Windows Version 1.4.2 64bits (Jan 23 2023)
OS: Windows 10 /64bit
I configured the XnviewMP for the Total Commander (10.52) Lister, but cannot open the Webp pictures on network share with Lister. The network share assigned to a letter (e.x.: P:\).

Effect: The Total Commander Lister open the Webp like text. Otherwise, open the same Webp file on local drive without problem.

To reproduce:
1. assign any network share to a letter (but this is not necessary)
2. set TC Lister Multimedia tab --> Graphics Path to XNViewerMP.exe (see attachments)
3. Try to open Webp picture on the network share with Total Commander's internal Lister

Actual behaviour (bug): <Current wrong behaviour of XnView>
I create a log file with ProcMon64, and I found a little path problem, attached the screenshot. The right path shown at the bottom of the screenshot.

Expected behaviour: open the picture on the network share.

are you able to use another Lister plugin without problem on shared drive?

Yes, the Imagine (https://www.nyam.pe.kr/dev/imagine/) works perfect, I use this everyday.

Edit: I made some more tests, and I think I found the main problem: the UTF-8 characters. I use Hungarian language, and the path contains a special Hungarian character: "ő". If I remove this charater from the path, the XnViewMP Lister can open the webp picture.

If you see the Process Monitor picture, the XnViewMP path replace the "ő" (U+0151 Latin small letter O with Double Acute) character to a Latin "õ" (U+00F5 Latin small letter O with Tilde), and because of this it cannot find the path.

1.4.3 64bits: same behavior, if is UTF-8 character in the path, cannot open the picture.

Thanks to your detailed description I can reproduce the problem.

This problem is supposed to be fixed in XnView MP 1.4.4. Please check and confirm the bug fix here.

Problem fixed in XnView MP 1.4.4.
Working fine with the Hungarian UTF-8 characters.
Thanks!
