1.4.2 64bits: TC viewer cannot open Webp on network share

[Scannia]

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.

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

Working fine with the Hungarian UTF-8 characters.
