[luatex] letterspacing in LuaTeX

[bulia byak]

Dunno if this will be helpful, but I do letterspacing thus:

\def\spaceone#1{\if#1*\let\nextspaceone=\relax\else\let\nextspaceone=\spaceone{#1}\hskip2.6pt\fi\nextspaceone}
\def\so#1{\bgroup\obeyspaces\spaceone#1*\unskip\egroup}%

You can adjust the amount of spacing in the hskip. Sure, this is a
hack with many limitations, but it works for my limited needs, and it
works in luatex. When \letterspacefont gets fixed, I will happily
switch to it.
