-- call
--
-- This function is usually useful for debugging template parameters.
-- Prefix parameter with backslash (\) to force interpreting parameter as string.
-- The leading backslash will be removed before passed to Lua function.
--
-- Example:
--    3 will return results of mw.log('a', 1, 2, 3)
--     \321  will return results of mw.logObject('a', 321, '321', ' \\321 ')
--
-- This example show the debugging to see which Unicode characters are allowed in template parameters,
--     return 97
--     return 65533
--     return 65533
--     return 0xfffd
--     return 0x007e
--     return 0x007f
--     return 0x0080
--     return 0x00a0
