Optional Techniques (advisory) for 2.5 L3 SC1

Additional Technology-Independent Techniques

• Providing spell checking for text input if applicable to the language.
• Checking byte of character and auto converting to expected byte for text input if applicable to the language.
  • For example, figures in Japanese can be either a single-byte character or a double-bytes character. If the user input a figure by a double-bytes character in a text field which must be a single-byte character, server-side program can detect the incorrect figure and convert it into the expected format.
