-- This package contains the routine used to convert strings to wide (wide)

-- This routine simply takes its argument and converts it to wide string
-- format, storing the result in R (1 .. L), with L being set appropriately
-- on return. The caller guarantees that R is long enough to accommodate
-- the result. This is used in the context of the Wide_Image attribute,
-- where the argument is the corresponding 'Image attribute. Any wide
-- character escape sequences in the string are converted to the
-- corresponding wide character value. No syntax checks are made, it is
-- assumed that any such sequences are validly formed (this must be assured
-- by the caller), and results from the fact that Wide_Image is only used
-- on strings that have been built by the compiler, such as images of
-- enumeration literals. If the method for encoding is a shift-in,
-- shift-out convention, then it is assumed that normal (non-wide
-- character) mode holds at the start and end of the argument string. EM
-- indicates the wide character encoding method.
-- Note: in the WCEM_Brackets case, the brackets escape sequence is used
-- only for codes greater than 16#FF#.
