Unicode Characters in ETL Strings [message #549291]

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 Andy,

We'll need to investigate this. Could you please file a bug report using
the link below and attach a minimal example that reproduces this?

Cheers,

Dimitris,

unfortunately I've been unable to reproduce the error in a simple example. The translation is correct in the small examples I tried. Our project is a good deal more complex, and difficult to simplify, particularly since it references a number of source metamodels.

What I can say though, is that it appears that the character, ∈ , in the fragment

Controller_pc ∈ Controller_pc_Set

is being encoded as,

Controller_pc âˆˆ Controller_pc_Set

instead of

Controller_pc 	∈ Controller_pc_Set

I can go ahead and write a bug report, but it might be difficult to provide a simple example.

cheers, Andy

Hi,
I also need to construct unicode maths in ETL. For example e ∈ S requires the memberof symbol. In Java I would write this using the escape code \ and unicode character number u2208 i.e.
var predicate = "e \u2208 S

However, it seems ETL cannot parse correctly with escape characters in strings. It gives me incorrect error messages as soon as I put \ in a string.

I also tried using the character directly but this does not work either.

Hi Colin,

Thanks for your reply. I'll have a look at this as soon as possible -
which might be a bit later than usual as I'm currently on holiday. Is
this a show-stopper for your work with ETL?

Cheers,
Dimitris
