Marcus,

Thank you for your encouragement. You are the first German user from whom we
have had any feedback!

(It is useful to post to "Snowball discuss".)

There was some confusion over codes a while ago, since I was using MS-DOS
Latin 1, but describing it as ISO-Latin 1 on the website (pure ignorance on
my part). But I think everything is in parallel now. The Snowball scripts
and the sample data sets use MS-DOS Latin 1. The documentation on the
website refers to MS-DOS Latin 1 where relevant. From 'Character codes' on
the main page you can get to the header files for ISO-Latin 1 and
instructions on how to adjust the Snowball scripts to use them. The code
values you quote are ISO-Latin 1.

- But perhaps I haven't understood your email, since '' is E1=225 in MS-DOS
Latin 1, 223 in ISO-Latin 1.

Martin
