8. The method of claim 1 , further comprising: generating a first table and a second table based on plurality of single byte service calls to a four byte conversion routine, each of the service calls including a character set pair, the character set pair including a first character type and a second character type for a same character; utilizing the first table to determine if a conversion is supported based on the character set pair; adding a converted value for the character set pair to the second table if the conversion is supported; the first conversion service includes a first routine for converting characters; and the first routine uses the second table to determine a conversion value for the character.
