Invalid character error while activating DSO - Please help

Question

Hi experts,
I'm getting invalid hex character error when loading a text infoobject in my DSO. Repairing data records in the PSA is not an option. Changing the data in the source system is also not an option. I've tried many of the methods suggested in other threads, but am unable to get it working (ABAP code, "ALL_CAPITAL" etc). We are on an unicode system.
Can someone provide some clean code to eliminate the illegal hex characters (00-1f) in my transfer rule routine. Basically, replace the illegal hex characters with space or an acceptable character.
Many thanks,
Anita S.

Hi,
I have used the below code for removing all unwanted chars from 0MATERIAL, that worked fine. You can modify it for ur need.
  CONSTANTS:
       G_ALLOWED_CHAR(58) TYPE C VALUE
         ' !"%&''()*+,-./:;<=>?_0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ'.
    data : E_ALLOWED_CHAR(58).
RESULT = SOURCE_FIELDS-MATNR.
    SHIFT RESULT RIGHT DELETING TRAILING SPACE.
    SHIFT RESULT LEFT DELETING LEADING SPACE.
    TRANSLATE RESULT TO upper case.
*RESULT = comm_structure-/BIC/ZCONTRTD.
    while RESULT ca '#'.
      RESULT+sy-fdpos(1) = ' '.
    endwhile.
    if RESULT(1) = '!'.
      RESULT(1) = ' '.
    endif.
    do.
      if not RESULT co g_allowed_char.
        shift RESULT+sy-fdpos left.
      else.
        exit.
      endif.
    enddo.
Thanks
