When you first run Rational Synergy, it creates a list of encodings in the file .ccm_merge.enc in your home profile directory. When you start a merge or compare operation, choose the encoding for the files from the encoding list. To shorten the list, remove encodings from the menu selection by editing the .ccm_merge.enc file, and then restart the Compare and Merge tool. To restore the full list, delete the .ccm_merge.enc file.
If you select an encoding that is inappropriate for the files being merged or compared, the tool might detect that and prompt you to select a different encoding. If the tool does not detect the incorrect encoding automatically, and you see the wrong characters displayed on screen, restart the Merge or Compare tool. Then, select the right file encoding explicitly.
Rational Synergy Compare and Merge does not support merging or comparing files with different encodings.
The tool also creates a .ccm_merge.dat file in your home profile directory. This file holds your default settings, including the encoding most recently used. To change the default Compare and Merge settings, edit the .ccm_merge.dat file.
