A new transformation format, called UTF-5 for Unicode is proposed. The resulting string of this UTF is within a [A-V][0-9] alphanumeric range. This enables legacy systems or protocols designed for alpha- numerical character set only to be multilingual enabled and inter- nationalized immediately. Example of such systems are the domain name system and email addresses.
