IIRC, CCSID 1208 (UTF-8) does not support BOM by default; that should be CCSID 1209 (and you guessed it: not supported on the system).

On the IFS you can start a stream file with the BOM (3 hex values) and than characters that will not be accepted in UTF-8 are acceptable.

But program variables are plain UTF-8, the BOM should have to be included to work.

How does it appear on the screen?  in debug? Copied to the IFS (CCSID 1208)?

Just wondering.

RPG nowadays can handle UCS-2 (data type ucs2; CCSID 13488), UTF-16 (data type ucs2; CCSID 1200) and UTF-8 (data type char; CCSID 1208). I was dealing with UTF-8.

The nice thing with UCS-2 (and single byte EBCDIC) is that every character takes a fixed number of bytes. In UTF-8 and -16 the number of bytes per character varies. I can imagine that that causes problems with the binary value in varying length fields.

I do not know how "exacting" the RPG documentation is, but I will point out
that UCS-2 <> UTF8.

I think you are right, Carel - problem with UTF-8 is, that BOM is
optional. Just another thing that makes this game so much fun!

Think you are dealing with the Byte Order Marker in UTF-8, which is
active for characters that needs more than 1 byte to be representable.

But it is still 1 character

My thoughts on this.

Kind regards,

Yes, I know. But in the case of ChrUtf the binary value contains 3,
while the string exists of 1 character (€) that uses 3 bytes. And the
documentation states that %len returns the number of characters.

A varying length field is always preceeded with an (invisible) 2 (or

Subject: %Subst and %len with UTF-8 data

Hello All,

While experimenting with CCSID(*UTF8) I found the following:

- I have a character variable BufIn with CCSID(*UTF8); containing
(amongst others) a Euro-sign (€; x'E282AC' in UTF-8)
- I have a variable length (length 10) character variable ChrUtf with
CCSID(*UTF8)
- When I try to get the Euro-sign into ChrUtf with 'ChrUtf =
%subst(BufIn: pos: 1)' ChrUtf contains x'0001E2'.

I am inclined to consider this a bug.

- I have another variable EurUtf - char(3) ccsid(*utf8) - which I
initialized with X'E282AC' (€)
- After 'ChrUtf = EurUtf' ChrUtf contains x'0003E282AC' and
%len(ChrUtf) yields 3; the number of bytes in the string; not the
number of characters.

I am inclined to consider this a bug as well.

I guess we need Barbara Morris to shed some light on this.
