[Feature Request] Add support to copy special characters to clipboard

[hXtreme]

It would be nice if the launcher could be extended to allow a user to search for a unicode char and then copy it to clipboard.

For example, if I want the greek letter theta then

1. Run launcher with super+/
2. Type unicode -- this causes the launcher to start listing unicode chars and additional information about them (symbol, name and codepoint)
3. Further type theta and press enter -- this should close the launcher and copy the appropriate char to clipboard.

If someone writes a plugin for it, it's already possible.
