How about having a single "unicode" line style, and then have a different \pset setting to determine exactly what chars to print? This wouldn't allow for programmability, but it seems better UI to me. This proliferation of unicode line style names seems odd.

After thinking I don't see any value for common user. Users like you, me, Merlin are able to parametrize output or patching source code.
Any parametrization expect some secure store, that will support exchange of styles. And it expect robust parser of unicode strings, or ascii strings with unicode escaped chars.
We cannot parse a escaped unicode chars now on client side, and cost of parser is higher of benefit externally parametrized borders.
