MES-4 Proposal: SECS

From: Markus Kuhn (
Date: Sat Aug 01 1998 - 18:33:16 EDT

The first draft for my Simple European Character Set (SECS)
proposal is now available for your inspection on

I want to carefully document how I created SECS and make this an
easily repeatable process (a basic ISO 9001 requirement), therefore
I also publish in

the software and auxiliary tables that created the above web page
using various publicly available tables. (Is similar software for
quality control purposes also available for MES-{1,2,3} ?). (Sorry
for the current lack of documentation for the uniset programme, but
if you understand Perl, I hope its function is fairly obvious from
the source code).

Please have a look at SECS and let me know what you think about
it and what you would like to see improved. Especially please have a look at
the table of characters that are in MES-2 but not (yet) in SECS and please
let me know which of those you think are important and why. I do not
want to add anything without at least a short rationale (e.g., which language
used it when and how frequently).

I would like to publish SECS as an Internet RFC rather soon.

Question: What is the difference between CIRCUMFLEX ACCENT (U+005e) and
anyway and why do we need both these characters in CP1252?
