Property tree export Error

Hi experts,

I try to export my property try with standard function in the customizing in "Set up Property Trees > My property select > Export" and I get errors.

I'm on UNICODE system. The export program return error: SYST_2_ISO_CODPAGE

The function EHSB_LBLS_UNICODE_ISO_MS return this error.

Have you ever had a similar issues?

Thanks
