Unfortunately does not work, but

in my fld "FIRST", which initially contains 4 unicode chars, outputs 2 
unicode chars.

Probably something to do with the fact that those are 4 double-byte chars.

This is where "Keeps Death his court and there the antic sits"; the 
antic being the problem
with double-byte characters:

"Scoffing his state and grinning at his pomp,
Allowing him a breath, a little scene,
To monarchize, be fear'd and kill with looks,"

and mysen fair forjeskit . . .  :(  an blackafrontit tae!  whit a scunner.

I was monarchizin a bit, so pleased with my unicode "exchange" script, but
the antic (as usual) scoffed most effectively at my self-assumed pomp.
