Exception 'CX_SY_CONVERSION_CODEPAGE '

Question

Hi friends,
In one of my bank transfer report i'm getting the runtime error CONVT_CODE_PAGE with the exception
CX_SY_CONVERSION_CODEPAGE.I don't what is the reason for this dump and how to correct it.So can anyone of u provide me help on this.
I'm attaching the detailed description of the dump below.
Short text
    A character set conversion is not possible.
What happened?
    At the conversion of a text from codepage '4103' to codepage '1100':
    - a character was found that cannot be displayed in one of the two
    codepages;
    - or it was detected that this conversion is not supported
    The running ABAP program 'ZFFOCN_A' had to be terminated as the conversion
    would have produced incorrect data.
    The number of characters that could not be displayed (and therefore not
    be converted), is 2. If this number is 0, the second error case, as
    mentioned above, has occurred.
Thanks in advance,
Vadivel.

Hi Eshwar,
I have posted the code below:
FORM DATEI_OEFFNEN                                                   *
die jeweilige Datei (TemSe/File) öffnen                              *
open current file (either in TemSe or file-system)                   *
FORM datei_oeffnen.
  IF hlp_temse CA par_dtyp.            "TemSe-Format
    PERFORM temse_oeffnen.
  ELSE.                                "disk-/tape-fmt on file-system
    PERFORM naechster_index USING hlp_renum.
    PERFORM fuellen_regut USING *regut-dtkey.
    ADD 1 TO cnt_filenr.
    hlp_filename    = par_unix.
    hlp_filename+45 = cnt_filenr.
    CONDENSE hlp_filename NO-GAPS.
    DATA i TYPE i.
    i = cl_abap_char_utilities=>charsize.
    IF i = 1.
      OPEN DATASET hlp_filename IN BINARY MODE FOR OUTPUT.
    ELSE.  " unicode system
      OPEN DATASET hlp_filename IN LEGACY BINARY MODE FOR OUTPUT.
    ENDIF.
    IF sy-subrc NE 0.
      IF sy-batch EQ space.
        MESSAGE a182(fr) WITH hlp_filename.
      ELSE.
        MESSAGE s182(fr) WITH hlp_filename.
        STOP.
      ENDIF.
    ENDIF.
  ENDIF.
