using isCharAlpha function from the win32 API that test if a caharacter is part from Alphabet or none we can test all characters of a string and return a string containing only alphabet characters, this is useful in Arabic language to trim kashida characters
funtion RemoveNonAlpha(srcStr : string) : string;
var i : integer;
begin
result:='';
for i:=0 to length(srcStr)-1 do
if isCharAlpha(srcstr[i]) then
result:=result+srcStr[i];
end
