Converting xString To String

Former Member — Fri, 08 Nov 2019 09:19:41 GMT

Dear Experts,

I tried this code below to convert hex into string but why did the result is becoming ###



  DATA conv TYPE REF TO cl_abap_conv_in_ce.

  DATA buffer(4) TYPE x.

  DATA text(100) TYPE c.

  buffer = '02'. " 

  conv = cl_abap_conv_in_ce=>create(

        encoding = 'UTF-8' ).

  conv->convert(

        EXPORTING input = buffer

        IMPORTING data = text ).

Please advice.

Thanks

In ABAP debugger and many UIs in ABAP, non-characters (example: byte hexadecimal values "00" to "1F" converted to UTF-8) are often represented with:

there a really usefull class for conversion CL_BCS_CONVERT

Do you try the opposite ?

data hexa type xstring value '02'.
data(dec)  = conv string( hexa ).
write dec.


dec = 2.
hexa = dec.
write hexa.

I do not see any problem. Your code works OK.

Your code is converting HEX value 02000000 (it is defined as X length 4 so it is = 02 00 00 00).
And result is corectly "control characte" U+0002. Which is not "printable" so SAP is displaying it as # in debugger.

Maybe you wanted to convert number 2 (DIGIT TWO) character ?
That is not 02 in HEX but 32 in HEX (U+0032). Check for example https://www.utf8-chartable.de/ or similar tables of HEX / UTF-8 characters...

In an ABAP Unicode system (any system with release >= 7.50 can only be Unicode), a character occupies two bytes. What you did is to convert four bytes with hexadecimal value 02.00.00.00 representing UTF-8 "characters" into ABAP characters. If your system is Unicode (UTF-16) big endian, you'll get four characters with hexadecimal value 0002.0000.0000.0000. With little endian: 0200.0000.0000.0000. You can see that in the debugger, you may display the hexadecimal representation of characters.

The answer is simply because the hex in abap is 16 bits and not the same with this one. everything in abap must be multiply by 100. If I adjust it then the # will not appear.
