Error description

• Change the data on the field that
  has CHECK(RB),CHECK(RZ) or CHECK(FE) attribute on 5250 screen
   and press Enter on the same field, auto fieldexit
   function works on HATS runtime by default.
   There is the runtime settings emulateFieldExit
   and the default value is true.
  
   I found that the additional symptoms on O type field and
   G type field.
  If input DBCS data with emulateFieldExit=true (default),
   the string is truncated.
  
   If the field length is 10byte,....
   and these fields have CHECK(XX) keyword on DDS
   and fieldExitRequired="true" on redered HTML
   O type:
     If input
       SO AA BB CC DD
     The string is sent to i/5 as
      SO AA BB SI  ( Two DBCS characters are truncated.)
   G type:
     If input
       AA BB CC DD EE
     The string is sent to host as
       AA BB
  HATS FIELD IS NOT CLEARED PROPERLY WITH EMULATEFIELDEXIT ENABLED
  ON FIELDS THAT HAVE EXISTING DATA

Problem summary

• ****************************************************************
  * USERS AFFECTED: DBCS users that have coded a DDS             *
  *                 attribute of                                 *
  *                 Check(RZ)- Right justify with Zeros,         *
  *                 Check(RB) - Right justify with Blanks, or    *
  *                 Check(FER) - FieldExitRequired.              *
  ****************************************************************
  * PROBLEM DESCRIPTION: When a DBCS user has a 5250 field       *
  *                      that is coded on the host as a DDS      *
  *                      field attribute of Check (RB, RZ, or    *
  *                      FER), and the field has data in it      *
  *                      already then new data entered and sent  *
  *                      to the host may be send unwanted data.  *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  This problem is a side effect of composite character support
  (DBCS), some Hiragana characters also are part of composite
  characters.  The length of the field that needed to be
  cleared was not properly calculated.  Therefore, data was
  being left that should have been cleared.
  

Problem conclusion

• Modified HostScreen.java to correctly calculate the length of
  the DBCS field, and modified lxgwfunctions.js to check if
  the character is a composite character or not.
