| Unicode Characters in ETL Strings [message #590915] |

Hi,
I wish to create a string in my target model that uses characters from the Unicode character set. In the ETL source I write,
pcInv.predicate := pcVar.name + " ∈ " + pcSet.name;
Currently the string that is output by my ETL translation does not correctly contain the Unicode character.
However, I also use Unicode characters in my source model, and they do get translated correctly (in this case they are just copies of the source) .
Any idea how to write Unicode in ETL strings so that they translate to Unicode in the target model?
Andy

Hi Colin,
This has been resolved offline with Andy. The solution is to define the
following toUnicode() operation
operation String toUnicode() {
var unicode = Native("java.lang.Integer").parseInt(self, 16);
var chars = Native("java.lang.Character").toChars(unicode);
return Native("java.util.Arrays").toString(chars).substring(1,2);
}
and rewrite the statement in question as follows
var predicate = "e " + "2208".toUnicode() + " S";
Cheers,
Dimitris
