Problem conversion of a text from codepage '4110' to codepage '4103'

Hi!

I upgrade my SAP version ECC 5.0 no Unicode to ECC 6.0 Unicode .

Now, when I execute some reports I get a dump because when I open my file with 'OPEN DATASET' and then READ and TRANSFER to another file the result is :

At the conversion of a text from codepage '4110' to codepage '4103':

- a character was found that cannot be displayed in one of the two

codepages;

- or it was detected that this conversion is not supported.

This dump is got when the file contain special characters like 'Á,Ñ,...)

I have searched some information and the source error I think is about UTF-16 to UTF-8 conversion. I look for some SAP notes but I don't clear what I have to do.

Thanks in advace.
