LO58141: INSTR AND STRCONV CAN'T HANDLE DBCS MINUS OF EUC-JP

APAR status

• Closed as fixed if next.

Error description

• By using LotusScript user want to handle the characters in file
  that is got on Solaris.
  But the charaset of the file is EUC-JP, LotusScript function
  can't handle DBCS minus "-"(SJIS code "817C", EUCJP code
  "A1DD", UTF8 code "FF0D") correctly.
  
  Instr function can't search the DBCS minus of EUC-JP charaset.
  Strconv function can't convert the DBCS minus of EUC-JP
  charaset.
  
  Sample code is the following:
  --------------
  Sub Initialize
   Dim txt As String
   Dim tmp As String
   Dim fileNum As Integer
   Dim fullhMinus As String
   Dim halfMinus As String
  
   fullMinus$ = "-" 'Fullwide Minus
   halfMinus$ = "-" 'Halfwide Minus
   fileNum% = Freefile()
  
      ' Import saved text file with EUC-JP charaset
      ' Fullwide Minus(0xA1DD)is inputted in the file
   Open "C:\Lotus\Work\euc.txt" For Input As fileNum%
  Charset="EUC-JP"
   Do While Not Eof(fileNum%)
    Line Input #fileNum%, txt$
  
          ' (1) display correctly?
    Messagebox "Imported character: " & txt$
  
          ' (2) Is the character fullwide Minus?
    If txt$ = fullMinus$ Then
     Messagebox "The character is 'Fullwide Minus'"
    End If
  
          ' (3) Can InStr search the Fullwide Minus?
    Messagebox "Result of InSt (1 is right): " & Instr(txt$,
  fullMinus$)
  
          ' (4) Can StrConv convert it to halfwide Minus?
    tmp$ = Strconv(txt$, 8)
    Messagebox "Result or StrConv: " & tmp$
  
          ' Check the result of converting with StrConv
    Select Case tmp$
    Case halfMinus$
     Messagebox "Result is 'Halfwide Minus'(convert is correct)"
    Case fullMinus$
     Messagebox "Result is 'Fullwide Minus'(not converted)"
    Case Else
     Messagebox "convert to unknown character"
    End Select
   Loop
   Close fileNum%
  End Sub
  --------------
  
  Steps to reproduce with sample DB:
  1. Put the sample DB on your Notes Data directory
  2. Put EUC-JP files on the C drive
      euc.txt
      eucutf8.txt
  3. Modify the file path of the agent
     Open "C:\Lotus\Work\euc.txt" For Input As fileNum%
  Charset="EUC-JP"
  4. Execute the agent
  5. You can see the EUC-JP file can't be handled correctly.
