Options Component Dialog box doesn't work

[colin]

We do have a bug report about this. Here’s a discussion that includes the steps needed to make it go wrong, and so to keep it working right, don’t do these steps!

Components don't appear in "Component Option" Window

I realized what you had asked now. The \u issue normally only happens in Windows, where it is very easy to accidentally name a file starting with ‘u’, and the \ comes from the Windows path. I am sure that is still a problem. On Mac you can make the same error happen by starting the file name with ‘\u’, which it seems is a legal filename, that happens to trigger the same Unicode related problem. So, no, it isn’t fixed.
