DBCS Enabling

1. Avoid assuming:

• fixed character size
  
  
• fixed lead byte range

1. Use CharPrev and CharNext instead of p-- or p++
   
   
2. Treat lead bytes and trail bytes as one unit
   
   
3. Handle WM_IME_CHAR
   
   
4. Store code page information with data
   
   
5. Check your algorithms for:

• caret positioning
  
  
• pointer arithmetic
  
  
• character code alignment
  
  
• word wrapping
