Default Render error that really must be a bug... (FIXED)

So I get a render error that I think really must be a bug.



R: has plenty space, so that is not the problem.

Turned out that the problem is an almost invisible space in the file name in the render dialog. Though you do not see it, it says "$project _3"with a space before the underscore. This makes Reaper tell me that there is something wrong, but there are two issues here:
  1. The file is incorrectly given as "Lack (mstr)3.wav" when it should be "Lack (mstr) _3.wav".
  2. The file name "Lack (mstr) _3.wav" is not an invalid file name on windows and should render fine. Note that there is already a space in the file name, which is since Win 98 (I think) allowed.

Reaper v6.35, W7x64

Can you show us what files are in R:\Renders currently? If there are many, just the ones beginning with "Lack" would be good!

Can you zip a minimal project that reproduces this issue and post here? Thanks!

Unfortunately I have to reply negatively to both of those questions.

R: is a RAM drive onto which I do intermediate renders, so all that is on there goes away when I shut down the computer. I can guess that files "Lack_3.wav", "Lack_3-001.wav" and "Lack_3-002.wav" were in R:\Renders. And I am quite sure that there were nothing like "Lack (mstr) _3.wav", or "Lack (mstr)_3.wav", as I had not managed to render the master project yet.

I tried now to replicate the issue by placing files named as above in R:\Renders, and putting the space before the underscore back in the file name to render to (that is "Lack (mstr) _3"), but everything renders fine.

Sorry.
If it happens again I'll be more careful to collect details.

I just realized... maybe it wasn't a space before the underscore, but some control character. That could explain why Reaper gives the wrong file name as "Lack (mstr)3.wav".

So I typed Ctrl+- (minus, the key down to the right next to the shift key and right above the Win key on Swedish keyboard) after "$project" which gave me what looks like a space in the file name, and then I typed a real underscore followed by a 3, and this replicates the problem. When reporting that it is unable to create the file, Reaper shows the file name as "Lack (mstr)3.wav".

I guess the render dialog edit boxes should filter out invalid control characters.

Here is a project that has this control code in the render file name. I am unable to render this, I get the error message as shown above.
