ML/I or Macro Processor One is a general purpose macro processor with a history going back all the way to 1966. It best known for its powerful text processing features that lead to it being primarily used on one hand for processing human-readable text for reformatting purposes and on the other as a preprocessor for programming code where code needed to be translated between programming languages that had some structural similarity but different syntax. While old and rarely updated it still has some advantages over more modern processors such as M4 or PPWizard or programming languages like AWK as it has better support for nesting and long lines of text.
Charset support
8 Bit ASCII (256 Characters according to current codepage). No support for Unicode or DBCS.

Supermac
Supermac was a macro processor developed by ML/I author Peter J. Brown in the 1970's that got quite a lot of interest when it was originally introduced, however unlike ML/I there has not been a version of it kept up to date and available for modern operating systems.
