[Linux?] Square bracket characters in pk3s not recognized

[plums]

GZDoom 4.5.0, 64-bit build on Linux.

Trying to load a pk3 with [ or ] for sprite frames results in an error, for example:

R_InstallSpriteLump: Bad frame characters in lump VILE%5E8

The frame doesn't get loaded. There isn't a problem with those frames when they're loaded from a wad.

Using [ or ] elsewhere also gives problems, for example in Decorate sprite definitions. I can't easily try a Windows build right now but I suspect that it might be a problem only in Linux.

Here's a test pk3 with an arch-vile recoloured red. (Walking frames omitted to meet the filesize limits.)

There are no [ or ] characters in your sprite names. Both 7-Zip and Windows Explorer show me filenames starting with "VILE%5". Probably a quirk of your ZIP archiver, but I'm not sure. It doesn't look like a GZDoom bug to me.

Yes, this looks like a ZIP tool producing DOS-safe file names. Nothing that can be fixed on the engine side.

Oh weird, it was just SLADE. Good to know though, thanks.
Oddly, the ^ frames got percent-encoded too, but loaded fine...

EDIT: In case anyone else experiences this problem and sees this post: In SLADE, go to Preferences -> General -> uncheck "Use percent encoding if needed outside of Wad Archives"

What's the point of that option? AFAIK no Doom port needs it.

This option is off by default AFAIK. It was added because Doomsday Engine needs it; while the default behavior is to do what ZDoom expects.
