Hi,

i am using the mentioned method to load a documentation as html, the problem is that I have several ä, ö, ü in the text which I can't display in the correct form, is there any possibility to display it ìn the right form?

I get this sign for the ä = Ã¼

I guess you need to use proper charset


call method r_html_viewer->load_data
exporting
   ....
   charset = 'ISO-8859-2'  "your country specific charset here

Where can I found my country specific charset?

Is ISO-8859-2 right for german?

Hello

ISO-8859-1 should be sufficient for the German language (see [ISO/IEC 8859-1|http://en.wikipedia.org/wiki/ISO/IEC_8859-1])

[Google says|http://a4esl.org/c/charset.html] for Western European countries it's ISO-8859-1

But not sure if you also don't have to provide encoding parameter in above method. Check with providing only charset first.

Hello,

I have now tried to use only the charset parameter with ISO-8859-1 but it doesn't work, what can I put in the encoding parameter because there is no documentation in the method to show what kind of values are allowed for the parameters.

I've newer used that too, so I am not sure. Try giving that ISO.. to encoding instead of charset .Also ensure these parameters are provided like


   type         = 'text'
   subtype      = 'html'

If that doens't work try directly showing your html page with method SHOW_URL without use of load_data first.

Marcin

You may also try giving internal abbreviation for codepage (4 digit number instead of character name)


CALL FUNCTION 'SCP_CODEPAGE_BY_EXTERNAL_NAME'
  EXPORTING
    external_name = 'ISO-8859-2'
  IMPORTING
    sap_codepage  = codepage.

DATA: char_codepage.

char_codepage = codepage.   "then try passing CHAR_CODEPAGE as encoding or charset

Hello MArcin,

unfortunately it doesn't work, I have to use the method load_data as I nedd the url which I get from this method.

I have now solve it as follows:

LOOP AT l_t_html_page INTO l_r_html_page.

REPLACE ALL OCCURRENCES OF 'Ü' IN l_r_html_page-tdline WITH 'Ü'.

REPLACE ALL OCCURRENCES OF 'ü' IN l_r_html_page-tdline WITH 'ü'.

REPLACE ALL OCCURRENCES OF 'Ö' IN l_r_html_page-tdline WITH 'Ö'.

REPLACE ALL OCCURRENCES OF 'ö' IN l_r_html_page-tdline WITH 'ö'.

REPLACE ALL OCCURRENCES OF 'Ä' IN l_r_html_page-tdline WITH 'Ä'.

REPLACE ALL OCCURRENCES OF 'ä' IN l_r_html_page-tdline WITH 'ä'.

REPLACE ALL OCCURRENCES OF 'ß' IN l_r_html_page-tdline WITH 'ß'.

MODIFY l_t_html_page FROM l_r_html_page.

ENDLOOP.

But I don't know if this is the best way?

Sorry for repliyng so late but I faced issues with posting a reply having html tags here.

In below code you must place HTML , BODY and META in b/w < > brackets. As I mentioned this caused a big trouble to reply to this message when using them.

The solution itself works fine


DATA: html TYPE REF TO cl_gui_html_viewer.
DATA container TYPE REF TO cl_gui_custom_container.

DATA: l_doc_url(255) TYPE c.
DATA: html_table TYPE TABLE OF char50.

APPEND ' html  body  ÜüÖöÄäß   /body   /html ' TO html_table.  "you need to provide your html b/w  HMTL  BODY  ...  /BODY /HTML  tags

CALL SCREEN 900.


MODULE pbo OUTPUT.
  CREATE OBJECT container
    EXPORTING
      container_name     = 'CUSTOM_CONTROL'.

  CREATE OBJECT html
    EXPORTING
      parent             = container.


  CALL METHOD html->load_data
    EXPORTING
      type         = 'text'
      subtype      = 'html'
    IMPORTING
      assigned_url = l_doc_url
    CHANGING
      data_table   = html_table.   "now this method will automatically append META  tags with correct charset (UTF-8) and hence will dipslay your German letters correctly. 
"without those  HTML  and  BODY  tags you will get those A1, as  META  tag can't be appended to HTML_TABLE correctly

  CALL METHOD html->show_data
    EXPORTING
      url = l_doc_url.

ENDMODULE.

Regards

Marcin
