Add 3D shape dialog doesn't load files ending in .STEP

[Nimo]

When trying to add a step model to a component footprint, the Select 3D Model dialog box does not display files ending in .STEP If the file extension is changed to .stp then the model is loaded correctly.

This isn't a major bug as there is an easy workaround, however some MCAD packages seem to output files with a .STEP extension by default which can be annoying.

Well, there is an easy workaround. Just rename the file. I think I have seen this mentioned elsewhere on the bugtracker, this may be a duplicate.

Really? I'm not expecting the bug to be set as top priority, but if the best answer is to repeat the workaround already suggested in the report then I'm not particularly impressed.

As for the duplicate, I did look but couldn't find anything. If it is a duplicate then I appologise for not looking properly.

I am not here to impress you. Please stop talking things personally (not speaking of just you, this is a comment for everyone).

In the meantime I have found some more info regarding this for future reference; the problem is in passing the name to OCE. We use UTF8 but OCE obviously doesn't pass that to the OS correctly so someone need to see how OCE handles wide chars on Windows.

I thought Cirilo was looking into this. I haven't seen anything unless I missed it. Maybe he can give us an update.

What I wrote earlier is the update. If anyone else finds the urge to dig deeper, feel free and go ahead.
