The problem may be not only limited to BlendLuxCore but involve LuxCore code too. It is a really un-tested area.

This is the material selector: https://github.com/LuxCoreRender/BlendLuxCore/blob/master/operators/material.py#L115
As far as I can see we are only using standard Blender API methods here (EnumProperty to generate the material list, window manager for the search popup).
So it is probably a limitation of the Blender API.

The ui_do_but_textedit warning/error is from Blender.

@PavelBlend please open a bug report in the Blender bug tracker.
My guess is that the WindowManager.invoke_search_popup method invokes an outdated Blender function internally which can't handle unicode.

It is similar to this old bug report: https://developer.blender.org/T35824

If they need it I can create a small example addon that shows the issue.

It may be the bug mentioned in the Python API docs here, that needs to be worked around for now:

Thanks, that was exactly the issue.
The ui_do_but_textedit warnings still appear, but they seem to be unrelated to the problem.
The search works now.
