AX 2009 Combined XPO not Importing Properly

We have been having issues getting the AX 2009 Automated TFS build process to work. The latest one we uncovered is the Combined XPO created does not import properly into AX. 

An example is the class method LedgerReport_Voucher_CN.initFromLedgerJournalTrans. We have a modification in the code here so it is one of the objects that gets added to the combined xpo. The first line of code in the class has the following defined constant

TmpVoucher_CN initFromLedgerJournalTrans(LedgerJournalTrans _ledgerJournalTrans)

{

   #define.Hyphen('—')

 The combined xpo has the following for this class method

 ***Element: CLS

 ; Microsoft Dynamics AX Class: LedgerReport_Voucher_CN unloaded

; --------------------------------------------------------------------------------

  CLSVERSION 1

   CLASS #LedgerReport_Voucher_CN

    Id 9137

    PROPERTIES

      Name                #LedgerReport_Voucher_CN

      Extends             #RunBaseReport

      RunOn               #Called from

    ENDPROPERTIES

    METHODS

      Version: 3

      SOURCE #initFromLedgerJournalTrans

        #TmpVoucher_CN initFromLedgerJournalTrans(LedgerJournalTrans _ledgerJournalTrans)

        #{

        #    #define.Hyphen('—')

        #

        #    LedgerAccountUtility_CN   accountUtility = new LedgerAccountUtility_CN();

After importing the combined xpo the Hyphen texts gets modified to

TmpVoucher_CN initFromLedgerJournalTrans(LedgerJournalTrans _ledgerJournalTrans)

{

   #define.Hyphen('—')

This issue does not happen if we export/import a project containing only this class. Does anyone know what the issue could be here?
