- -- This routine simply takes its argument and converts it to wide string
- -- format. In the context of the Wide_Image attribute, 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.
