Special characters in Smartforms

Hi,

I'm working with webdynpro abap and in my application I have to generate a smartform which one has been created and converted to a PDF file.

In the conversion routine, some special characters are loosing the properties itself, for example: the characterΩ has been transformed in © and I don't know why this is happening.

The function that I'm using to generato the pdf file is the code below:

CALL FUNCTION 'CONVERT_OTF'
        EXPORTING
          format              = 'PDF'
        IMPORTING
          bin_file             = e_result
        TABLES
          otf                    = t_out-otfdata
          lines                 = t_saida
        EXCEPTIONS
          err_max_linewidth = 1
          err_format        = 2
          err_conv_not_possible = 3
          err_bad_otf      = 4
          OTHERS         = 5.

And after I take the bin file that the function returns and use the static method from the cl_wd_runtime_services class:

cl_wd_runtime_services=>attach_file_to_response(
    i_filename      = 'Calibracao.PDF'
    i_content       = v_pdf
    i_mime_type     = 'application/pdf'
    i_in_new_window = 'X'
    i_inplace       = 'X'

).
