% TEX/LATEX $VER: ECMA94.STY 1.7 (3.1.1995)
%
% SYNOPSIS:
%    Conversion of umlauts and special characters of the
%    ECMA-94/ISO-Latin-1 charset for plain TeX with the
%    encoding of Computer Modern Font.  ECMA-94 seems to
%    be a standard charset for many conputers and printers.
%    Some (but not all) characters with codes higher than
%    code 127 are replaced by their TeX equivalents.
%    This encoding is *different* to the DC encoding, which
%    is very popular in the international TeX community.
%
% DATE OF CREATION:
%    11.01.94: Derived from AMIGA.TEX by Georg He{\ss}mann (V1.0)

%
% CHANGES:
%    12.01.1994: Portable encoding with ^^xx notation for all systems
%                relying on ECMA-94/ISO-Latin-1.  Intermediate systems
%                won't destroy its usability. (V1.1)
%    14.01.1994: $^1$ added for ^^b9 (V1.2)
%    15.03.1994: `\Cstringchars' implemented for use with
%                the CWEB macros (V1.3)
%    27.07.1994: Two `\lccode' and `\uccode' bugs fixed.  (V1.4)
%    25.10.1994: Renamed for LaTeX package support.  (V1.5)
%    24.12.1994: Some more characters added.  (V1.6)
%    03.01.1995: Works with LaTeX again.  Several modifications
%                according to Alain Aubord's `codepage' package.  (V1.7)
