The same character keyed in different keyboards may be represented by a board to another is not only not unique, it is also not necessarily one-to-one. For example, o may be keyed as one character or as three characters -- " o RBS - ", where RBS is a required backspace. In addition, the conversion must be case independent. The conversion of a character to upper or lower case is language dependent. For example, in National French, it is inappropriate to convert lower case accented characters to upper case with accent. Thus, "e" converts to "E". The following solution to the above problem is disclosed: 1) Define word delimiter codes which include punctuation. Thus, " SP w o r d SP " and " ( w o r d ." will compare equal. 2) Convert each character to a unique code (font code).
