sorry, this a plain TeX question (didn't read the interesting chapters
of the TeXbook).  Are lccodes language dependent?  I can only see a
single table tex.lccode in LuaTeX.

What I want is to get the lccode of characters from glyph nodes, which
might be of various languages.  I'm currently doing something like

  lc = tex.getlccode(n.char)

but shouldn't n.lang be taken into account in the conversion?

And BTW, what information is provided in field uchyph in glyph nodes?

Best regards,
Stephan Hennig
