X-Authentication-Warning: sirppi.helsinki.fi: peuha owned process doing -bs Date: Wed, 16 Feb 2000 12:24:41 +0200 (EET) From: Esa A E Peuha Sender: peuha AT cc DOT helsinki DOT fi To: djgpp AT delorie DOT com Subject: Problems with Emacs 20.5 Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Reply-To: djgpp AT delorie DOT com Emacs 20.5 has some problems with international support on MS-DOS. First, the quote "MS-DOS doesn't allow use of several codepages in a single session. Instead, MS-DOS loads a single codepage at system startup, and you must reboot MS-DOS to change it" from the manual is not true; DOS does allow more than one codepage to be loaded at startup, and they can be changed with the CHCP command. Second, entering non-ASCII characters doesn't work. For example, typing ``C-x 8 " A'' produces code 196, which is the code for A-umlaut in iso-latin-1, but it is interpreted in the context of the current code page; in code page 437, this is the code for vertical line drawing character, which maps to iso-latin-1 code 173 (soft hyphen). For this particular character, it is possible to work around this problem by saving the file as cp437 and reading it as iso-latin-1, but generally it's impossible (``C-x 8 " a'' produces code 228, which is uppercase sigma in cp437; as there is no such character in iso-latin-1, the file gets code 127 both as cp437 and iso-latin-1). -- Esa Peuha student of mathematics at the University of Helsinki http://www.helsinki.fi/~peuha/
