Error description

• In ClearCase Remote client 7.1.1, when an extended ASCII file
  encoded as UTF8 is stored in ClearCase
  as an element type that is NOT based on type manager
  'utf8_file_delta' and
  the CCRC preferences are NOT explicitly set to use UTF8 as Text
  File Encoding
  Then using 'CCRC Integrated (UTF8)' Compare/Merge tool to
  compare versions results in garbled text.
  
  Steps to Reproduce:
  
  1. Use a VOB that is set up for managing UTF8 files in a 7.0.x
  and earlier environment
     That is, UTF8 files manged as binary_delta_file or
  compressed_file
  2. Access files in CCRC 7.1.1.x, with default Compare/Merge tool
  set to 'CCRC Integrated (UTF8)'
  3. Invoke 'Compare to Predecessor'
  
  
  Workarounds:
  
  1. Implement 'utf8_file_delta' type manager (In a fully migrated
  ClearCase 7.1 environment)
  a. Create a new element type based on type manager
  'utf8_file_delta'
  b. Identify all UTF8 files and chtype them to the new element
  type
  c. Ensure that all new files that will have UTF8 content also
  get managed with the new element type
  
  2. Set the Eclipse workspace 'Text File Encoding' to 'UTF8'
  CCRC ? Window ? Preferences... ? General ? Workspace ? 'Text
  File Encoding'

  When determine the encoding of the file,if the type manager
  of the file is not included in[utf8_file_delta,
  utf16le_file_delta, utf16be_file_delta, utf32le_file_delta,
  utf32be_file_delta], then will use the encoding that set in
  Eclipse "Window?Preferences?General?Workspace" , So to avoid
  the problem, change the encoding to UTF-8 if none is found
  in the above specified type manager.
  

Problem conclusion

• Delivered in ClearCase versions 7.1.1.5 and 7.1.2.2.
