General Points of Internationalization Programming
Character Comparison

When you comapre characters (mostly declared as char data type), you should not use the operator such as '>', '<' and '='.
Each programming language provides functions for character/string comparison, so using them is recommended.
Some of the main functions are listed below.

• Standard C Programming
  

  strcoll
  wcscoll
  

• Java Programming
  

  String.equals
  String.comapreTo
  String.compareToIgnoreCase
  Character.equals
  Character.comapreTo
  Character.compareToIgnoreCase
  

• .NET Programming
  

  String.Compare
  String.CompareTo
  String.CompareOrdinal
  

• VC++ MFC Programming
  

  CString.Compare
  

• Visual Basic 6.0 Programming
  

  *Visual Basic 6.0 compares strings with operators ("<", ">", "=", and "Like").
  Comparing mode can be switched to binary or text by Option Compare statement.
  Option Compare Binary means "AAA" < "aaa".
  Option Compare Text means "AAA" = "aaa".
  

• JavaScript Programming
  

  *JavaScript compares strings with operators ("<", ">", "=").
  
  You should note that non-ASCII character comparison (e.g. Japanese) with operators "<" or ">"
  sometimes returns different results in each browser.
  if possible, you'd better avoid general character comparison in JavaScript.
  
  charCodeAt, the function to return the code of characters in strings, 
  sometimes returns different results based on character encodings used by browsers too, 
  and its usage is not recommended for non-ASCII characters.
  

• ActionScript Programming
  

  flash.globalization.
  Collator.compare
  Collator.equals
