[Bug: 21.4.22] weird file corruption with utf8 charset

Richard KLINDA writes: Mule-UCS is deprecated. I don't think there has anybody who actually knows that code working on it for 15 years. If you want to use XEmacs with Unicode, the use of XEmacs 21.5 is highly recommended. I don't have an XEmacs 21.4 to try to reproduce right away, but looking at your example file, the first instance is exactly on a 65536 (2^16) byte boundary (the 11th) and the later instances occur at intervals of 65537 bytes after that. There are three possibilities I can think of: 1. there's an old bug due to "const propagation" in C that caused problems with stream output at buffer-size intervals (usually a power of 2), but that was fixed a long time ago; 2. the CCL byte-code interpreter used to implement Mule-UCS uses 16-bit arithmetic and it might be buggy; and 3. finally the Mule-UCS coding system written in CCL might be failing to clean up after itself when called repeatedly or some similar bug. I'll try to build an XEmacs 21.4 and reproduce but I doubt I'll have time to take a close look at the code for a while (I'm not familiar with it). Maybe Aidan has some idea, though. _______________________________________________ XEmacs-Beta mailing list XEmacs-Beta(a)xemacs.org http://lists.xemacs.org/mailman/listinfo/xemacs-beta
