Convert an OpenEdge database to UTF-8 using the PROUTIL CONVCHAR utility

This topic describes the steps to convert an OpenEdge database to UTF-8 using the PROUTIL CONVCHAR utility.

To convert an OpenEdge database to UTF-8 using the PROUTIL CONVCHAR utility:

CAUTION: Before you begin, back up your database.
  1. Convert the database to UTF-8 using the following syntax: 
    proutil database-name -C convchar convert utf-8
  2. Load the collation data definition (.df) file using the syntax for your specific operating system:
    Windows syntax 
    %DLC%\prolang\utf\filename.df
    UNIX syntax 
    $DLC/prolang/utf/filename.df

    For the UTF-8 BASIC collation, use the _tran.df collation data definition file. For an International Components for Unicode (ICU) collation, use one of the collation data definition files prefixed with "ICU" or "ICU_48" (such as ICU-cs.df used for Czech databases). For more information about character processing, see the README file in the directory OpenEdge/prolang.

  3. Compile, store, and apply the UTF-8 word-break rules to your database. For complete instructions, see Compile, make available, and apply the UTF-8 word-break rules to a database.
  4. Rebuild the indexes using the following syntax: 
    proutil database-name -C idxbuild -cpinternal utf-8
