string to xstring => xstring to string

  • ejemplo 1
  lo_c2x = cl_abap_conv_out_ce=>create( encoding = 'UTF-8' ).
  lo_c2x->convert( EXPORTING data   = l_string
                   IMPORTING buffer = l_xstring ).

" convert xstring to string for output
cl_abap_conv_in_ce=>create( input = l_xstring )->read( IMPORTING data = l_string ).
  • ejemplo 2
l_xstring = cl_abap_codepage=>convert_to( source = l_string codepage = 'UTF-8' ).

  CALL METHOD cl_http_utility=>if_http_utility~decode_utf8
    EXPORTING
      encoded   = l_xstring
    RECEIVING
      unencoded = l_string.

Codepage encodings

  • Ver Tabla TCP00 - Catálogo de code page SAP

Ejemplo: 

4110 - Unicode UTF-8
1100 - SAP internal, like ISO 8859-1       (00697/00819)
