So what am I missing in my code, Jonathan ?  I have added a \hyphenchar, 
removed the pointless (and dysfunctional) \showhyphens), but still get 
no hyphenation —

% !TeX Program=Ini-XeTeX

\catcode `\ = 10
\catcode `\         = 10
\catcode `\{ = 1
\catcode `\} = 2
\catcode `\^ = 7

\tracingonline = 1
\tracinglostchars = 2

\font \tenrm = "Amiri"
\tenrm
\hyphenchar \font = `\‐

\lccode "200D = "200D
\catcode "200D = 11
\patterns {^^^^200d1^^^^200d}

\hsize = 0 pt
bla^^^^200d^^^^200dbla

\end
