Abstract
A method of using a computer (11) to translate a source text file (10) to a destination text file (15). The source text file (11) is written with code points from one code page; whereas the destination text file (15) is written with code points from another code page. The computer (11) accesses a state table library (13a) and executes a translate process (13b). A state table (25) from the library (13a) has rows of cells, each row being associated with a different state. Each cell contains or implies a next state and may also contain an output code point sequence. During translation, the table (25) uses a current state to select a row and uses an input code point sequence from the source text file to select a table entry. The input code point sequence is processed until an output code point is produced. For multi-byte translations, the table (25) has a cells containing a state that results in reprocessing of input code point sequences.
