Reginald does not currently support UNICODE. Standard REXX doesn't support UNICODE. It uses ANSI-only. All strings in REXX must be ANSI, and so must the contents of a script.

I'd like to do a version of Reginald that is UNICODE, but then it wouldn't support normal REXX scripts. In fact, I'd like to do a version of REXX that alters some elements of the language to pull out a few advantages that Java and C have in their syntax, as I described in another post on this BBS.

But in the current version of Reginald, if you do happen to encounter a UNICODE string from somewhere (ie, reading it from a file, or being given it from some OS function you FUNCDEF), then Reginald does already have a built-in function to convert a UNICODE string to ANSI (and vice versa). But just don't try to use that UNICODE string with any string functions like POS, LENGTH, etc, or you'll get results you don't expect. Once you convert it to ANSI, then you can use the converted string like any other REXX string.

The CONVERTSTR function converts a string from ANSI to UNICODE, or vice versa.
newstring = convertstr(string, options)
string = The string to convert.
options = Any of the following:

   'U' = 'string' is a UNICODE string to convert to ANSI. If you don't specify 'U', then 'string' is an ANSI string to convert to UNICODE.
   'V'    = 'string' is the name of a variable containing the string.
   'Z' = 'nul-terminate the resulting string'.

   The 'V' option ('string' is the name of a variable containing the
   string) for CONVERTSTR function returns a null string.

   You should also check if the 'Z' option ('nul-terminate the
   resulting string') is working.


   Also the CONVERTSTR function is not documented in rexxbook.
