I think Customer Support should weigh in here.
Do witango string manipulation functions (<@LEFT>, <@LOCATE>, <@REGEX>,
<@REPLACE>, <@RIGHT> , <@SUBSTRING>) use:
a) a fixed character encoding (e.g. LATIN-1) set at compilation
b) the character encoding of the environment (LANG=UTF-8, for example
on linux)
c) a user selectable encoding, perhaps using iconv to do the mapping
d) it doesn't matter for single byte character sets. Witango compares
bytes. It's the developer's responsibility to use the same encoding on
both sides of a string comparison.
If (c), how does one select the character set?

The question is, will witango honor that encoding tag, and actually
encode correctly. I am rewriting some webservices, and this was a
major issue for me before, because witango would ONLY encode as
ISO-8859-1, I am writing an application to test this, be done in a
bit, and will post.

Hi Bill,
Doesn't xml require utf-8?
No. That's what the prolog and instructions are for. Example:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<someXml />
There are several hundred different character sets that can used with
XML I think. If specific instructions are not given, then typically
this information is inherited from the platform where the XML
originates.
And as we all know, Tango/Witango has a default character set of
ISO-8859-1 (on Windows anyway).
Like I mentioned, I think one of the newer releases of Witango
provides support for UTF-8, but I can't remember which version
because I just don't spend time in Witango anymore.
Anyway, going to the issue of "umlauts, etc." from last week, if the
problem is how the character is rendered on the client, it
could be due
to the encoding specified in the http header of the html <head>.
It depends on the consuming application. When it comes to XML, the
application may decide to honor the XML instructions, or it may only
honor the HTTP instructions that delivered the XML.
But I suspect there may also be a lingering gotcha in the Witango
string manipulation tags. I presume that Witango string
manipulation
uses the character set specified in its environment variable (for
whatever user it's running as). But if you want to
manipulate strings
in a different character set, you're in trouble.
Yes, this could be a factor. If the DOM variable is passing through
some other bit of code and logic for some additional processing, the
UTF-8 encoding could get lost and revert the characters back to
ISO-8859-1.
That is why entity encoding is often used, e.g., €, because it
is less likely to be affected by conversion (accidental or on
purpose).
Hope that helps.

Hi folks,
By default Witango supports ISO-8859-1 character sets (basic latin
characters), but newer versions apparently support UTF-8, which is
more extensive.
Note, I don't remember which version
introduced the UTF-8 support.
In theory you should be able to just assign the encoding
set when your
DOM variable is assigned, something like:
<@ASSIGN local$myVar value="<@dom value='<?xml version="1.0"
encoding="UTF-8" ?><MyXml anAttribute="some characters" />'>">
So your success may depend on what version of Witango you
are running.
And as for encoding your character as € as your
alternative? This
is standard XML practice - get used to it.
Have a nice day :-)

I have the same problem since I have install Witango 5.5
Server. In prior versions it have work fine.
One way for a work around:
<@REPLACE STR="<@elementvalue object=user$allstringsdom
element='root().id(Feld_@@local$Step)' encoding=none>"
FINDSTR="?" REPLACESTR="€">

Subject: Witango-Talk: support for @DOM encoding
Hi Folks,
I wonder would anyone be able to tell me what character
set the @DOM tag supports?
I assign the Euro symbol (€) as part of the XML
document using the @DOM tag, but when I read the value back
out of the XML document it appears as a ? rather than the
Euro symbol. This is causing me a bit of a problem and I am
wondering if theres a way around it. Replacing the Euro
symbol with the HTML equivalent € appears to be too
complicated in my scenario.
Thanks
Mike.
