Send special character by mail

Question

We are creating an XML spreadsheet that is sent by mail, and we are requested to show in a cell the special character Delta (u0394).
The overview of the process is the following:
- We create an XML file through IF_IXML interface, with enconding UTF-8 Little Endian.
- Then we render XML into an internal table.
- At last, we send the XML spreadsheet (the internal table) as an attached file by mail through SO_NEW_DOCUMENT_ATT_SEND_API1.
The problem we are facing is the following:
If we try to put Delta (u0394) as a character in a data tag (it's a variable of type String), SAP is turning it as '#', and not showing the character.
  DATA: o_cell TYPE REF TO if_ixml_element,
        o_data TYPE REF TO if_ixml_element,
        v_string TYPE string.
* Crea una celda
  o_cell = o_xmldoc->create_simple_element( name = 'Cell'
                                             parent = o_row ).
v_string = 'u0394'.
*   Crea un dato
    o_data = o_xmldoc->create_simple_element( name   = 'Data'
                                               parent = o_cell
                                               value  = v_string ).
When you open the file in Excel, the '#' character is shown instead of  'u0394'.
How can I show that Delta character (u0394) in the XML spreadsheet file I am sending?
Please tell me if more information is needed.
Thanks in advance,
Martin

Answer 1

I tried like you said:
  DATA: o_cell TYPE REF TO if_ixml_element,
        o_data TYPE REF TO if_ixml_element,
        v_string TYPE string.
* Crea una celda
  o_cell = o_xmldoc->create_simple_element( name = 'Cell'
                                             parent = o_row ).
v_string = '& #916;'.                                           'Added a space in the middle to show the HTML entity code in the forum
                                               parent = o_cell
                                               value  = v_string ).
But SAP is tranforming my XML text to:
<Cell>&amp;#916;<Cell>
( &amp; is the HTML entity for '&')
How can I put Delta character so that SAP turns it in the right HTML entity &#916;
Or how can I manage so that the cell value generated is:
<Cell>&#916;<Cell>
