Background documentation Code Page in ICF  Locate the document in its SAP Library structure

Each application must relate the representation of the texts in its response document (in the body of the document) to a suitable code page. The following example shows you how to convert a text into the UTF-8 code page and present it as part of a HTML page. For this purpose, the header field Content Type is set to ‘text/html’ and the character set is set to utf-8. This tells the partner how to represent the HTML text.

 DATA: cvto_utf8 TYPE REF TO cl_abap_conv_out_ce.

 DATA: codepage  TYPE string.

 DATA: html_text TYPE string.

 DATA: html_utf8 TYPE xstring

 

 codepage = server->request->get_form_field( 'codepage' ).

 

     IF codepage = '1'.

      TRY.

          CALL METHOD cl_abap_conv_out_ce=>create

            EXPORTING

              encoding = 'UTF-8'

            RECEIVING

              conv     = cvto_utf8.

        CATCH cx_parameter_invalid_range .

        CATCH cx_sy_codepage_converter_init .

      ENDTRY.

 

      CALL METHOD server->response->set_header_field(

             name  = 'Content-Type'                         "#EC NOTEXT

              value = 'text/html; charset=utf-8' ).

 

      TRY.

          CALL METHOD cvto_utf8->write

            EXPORTING

              data = html_text.

        CATCH cx_sy_codepage_converter_init .

        CATCH cx_sy_conversion_codepage .

        CATCH cx_parameter_invalid_type .

        CATCH cx_parameter_invalid_range .

      ENDTRY.

* conversion into UTF-8 unicode code page

      html_utf8 = cvto_utf8->get_buffer( ).

 

* set body as hexadecimal string

      CALL METHOD server->response->set_data( data = html_utf8 ).

 

    ELSE.

*   automatic conversion of SAP_UC to utf-8 in a unicode system

      CALL METHOD server->response->set_header_field(

         name  = 'Content-Type'

         value = 'text/html' ).

 

      CALL METHOD server->response->set_cdata( data = html_text ).

    ENDIF.
