HD25700: INCORRECT ENCODING OF NON-ASCII CHARACTERS IN P21 FILES CREATED BY LCA

APAR status

• Closed as program error.

Error description

• DETAILED DESCRIPTION:
  The STEP part 21 files created by Enovia LCA do
  not encode non-ascii
  characters correctly.
  I have only tested using swedish special characters
  ﾨ,ﾨ and ﾨ, but the
  error is likely to affect other characters as well.
  Enovia LCA uses the format '\X2\hh\X0\' where hh
  is a one-octet
  hexadecimal number. This is wrong. The standard
  says '\X2\hhhh\X0\',
  where hhhh is a two-octet hexadecimal number.
  There is also a discrepancy between the P21 writer
  and the P21 reader of
  Enovia LCA. The reader requires the format '\X2
  \hhhh\X0\' which means
  that the IEnovIn.sh (VPMImporCDM) program can
  not read its own temporary
  files.
  If you do not wish to use the ISO-10646 character
  set, use the '\X\hh'
  format to encode ISO-8859-1 as described in
  chapter 6.3.3.3 of
  ISO-10303- 21.
  Chapter 6.3.3.2 "Encoding the character sets of
  ISO 10646 within a
  string" from ISO standard 10303-21:
  The control directive reverse solidus capital letter X
  digit two reverse
  solidus "\X2\"shall be used to indicate that the
  following sequence of
  multiples of four hexadecimal characters shall be
  interpreted as
  encoding the two-octet representation of characters
  from the BMP in ISO
  10646.
  The encoding in a string in the exchange structure
  shall be as follows:
  ? each character in the representation of 10646 to
  be encoded shall be
  converted to two 8-bit bytes as specified in ISO
  10646;
  ? each of the two resulting 8-bit bytes shall be
  encoded as two
  hexadecimal characters in the basic alphabet
  corresponding to the
  graphic representation of the hexadecimal digit.
  Example:
  Original text, in Swedish: 'EMBALLAGE/RACK
  LﾨDA'.
  Encoded according to ch 6.3.3.1 of ISO-10303-
  21: 'EMBALLAGE/RACK
  L\S\EDA'.
  Incorrect encoding by Enovia
  LCA: 'EMBALLAGE/RACK L\X2\c5\X0\DA'.
  Correctly encoded according to ch 6.3.3.2 of ISO-
  10303-21:
  'EMBALLAGE/RACK
  L\X2\00c5\X0\DA'.
  .
  Step by step scenario:
  None - see above full description.
