When downloading a mod from the mod portal, it replaces the spaces with %20. However, when placed in the mods folder, the game crashes. Making it an actual space fixes the problem.

For example:
Download: Squeak%20Through_1.1.8.zip
What works in game: Squeak Through_1.1.8.zip

I don't think that we should allow spaces in mod name.
It can be in the readable name, but the mod name should be without spaces.

Bit too late for that now, isn't it? https://mods.factorio.com/mods/Raeon for example has spaces in all mod names, they would have to reupload all their mods, and couldn't even migrate between versions due to the name change.

Thanks for the report however I can't reproduce what you're saying: when I download squeak through off the mod portal it downloads as "Squeak Through_1.1.8.zip" and if I manually rename it to include %20 instead of the space it gives a proper error about the name being miss-matched.

What browser are you using?

I can confirm the behaviour on Firefox Quantum 57.0.3, but since the link on the mod portal has a space in it and the %20 is the browsers doing, I'd say this is outside of your control, other than making a policy decision to not allow spaces.

I see, in that case you'll need to file a bug report with the FireFox devs to have them fix the issue on their end.

I double checked RFC 3986; space is not in the allowed characters set of a URI/URL and must be %encoded, so technically the mod portal is deviating from standard by supplying a link with an unencoded space. Since it's not standard, that's why there is variability in how different browsers handle the situation. See also this stack overflow question/answer.

To be honest, I don't really care what the RFC says. The link you provided says it was written in 2005 which means it's super outdated. If a browser can't handle a simple file download without mangling the file name that's the browsers problem. Chrome, IE and Edge handle the downloads without any issues. Additionally the in-game downloader has no such issues.

The download attribute takes an optional filename value which specifies the filename to use when saving. https://www.w3schools.com/tags/att_a_download.asp .

No idea whether mods.factorio.com is specifying it.

Oh, so this is a browser error, I see.

Worth noting is that for quite a long while, this error did not exist, and the mod portal happily provided the proper filenames when downloading in Firefox. However, now Firefox is having issues with naming... so perhaps something in the new Firefox 57 has changed the way it handles the interaction with the mod portal.

Is not, RFC3986 the is current one, otherwise there would be a "Obsoleted by: number" somewhere at the top.

It might be a case of Firefox adhering to the spec to the letter while other browsers are more forgiving to non-conformant websites.

The download link isn't public, you need an account, correct? then a bug report wouldn't be useful. If there's a download with a space that works for anyone then I can submit a bug report.

Seems to be fixed!
