Hi all
While I may change my mind in the future, I've pretty much decided to abandon
the project for now, for these reasons:
1. Mongo DB data is UTF-8 and not even ASCII. An EBCDIC version is thus
irrelevant and not needed. This is different then the situation with the PCRE
library where EBCDI

Timothy is right - as long as your program doesn't call services that
require EBCDIC names, you don't need EBCDIC.
