As you mention a csv file I'm wondering if your encoding is wrong: I.e. when you create your instance of cl_abap_conv_in_ce you don't specify the encoding of your source hex string, so that means the default encoding is used, which should be UTF-8 in your case. So if your csv file is not encoded in UTF-8, specify the correct encoding in the create method and see if that helps.
Depending on how you get the file contents you might actually be able to combine the file retrieval with the conversion in one step. E.g. if the file is read from the application server you could specify the used code page via [open dataset ... in legacy text mode ... code page|http://help.sap.com/abapdocu_70/en/ABAPOPEN_DATASET_MODE.htm#&ABAP_ALTERNATIVE_4@4@]. Similarly method gui_upload of class cl_gui_frontend_services also allows you to specify a code page.
If all of this doesn't help, post some further details on your file (e.g. sample content & encoding) and possibly add some further details from the exception you're getting. As you mention a Unicode system it basically means that we should be able to convert all characters without any problem as long as we specify the correct source code page.
