Teckit Map Unicode Editor: is there a line I can use to convert ASCI latin letters to Unicode

Is there a line, or few lines, that I can use to convert regular latin letters (without diacritics) to Unicode?

The converter that I am working on will, hopefully, convert legacy materials for a language using latin characters to unicode. I thought there was a way involving just a line or two that instructs the converter to take Ascii A,a,B,b,C,c… and convert it to Unicode, but do not remember what it is. Anybody know?

Thank you,
Scott

Perhaps something like:

; (1) The first 128 characters follow the standard mapping.
ByteClass [First128] = (   0x00 .. 0x7f   )
UniClass  [First128] = ( U+0000 .. U+007f )
[First128]	<> [First128]

Thank you David, that seems to work. I’ll find out for sure when I test this converter on a document.
