You can use Lua to create a list of all character combinations. The 
convert function
takes three argument, the first is the conversion method, the second the 
conversion
value and the third the language (optional and only used by certain 
conversion methods).


\starttext

\startluacode
for i = 1,27 do
     for j = 1,27 do
         context(converters.convert("a",i,"es"))
         context(converters.convert("a",j,"es"))
         context.par()
     end
end
\stopluacode
