This is just standard lower() and upper() combined in 1 function.

This one was interesting for me.

First, I had to remove all Russian routine names from 'wildcarr.e',
because my Euphoria complained. Then I run the following test program:

include wildcarr.e
constant CP = {"dos","win","koi","iso","mac"}
sequence s
s = "heLLo"
for i = 1 to length(CP) do
   printf(1, "'%s'\n", {case_ru(0,s,CP[i])})
end for

This test program just printed 5 times "heLLo" (German Windows 98).
Thanks for the suggestion anyway.
