Re: [Bug: 21.5-b24] Problems with coding systems autodetect

Ben, this is about a bug report that I sent to xemacs-beta five days ago; coding autodetection for files with German texts does not work.] In private email, Lutz Euler pointed out that this was discussed already in January. There, Steve mentioned that the problem does not occur if one sets the language environment. That's not the case here. If I set-language-environment to "Latin-1", the autodetection still does not work. ("German" doesn't work either; but I wouldn't want to use that anyhow as it changes XEmacs' idea of my locale.) The problem at hand is that there are words with several local characters (from the GR plane) in a row. When iso2022_detect() in mule-coding.c sees that, it sets all ISO coding categories to `somewhat-unlikely'. Lutz posted a three-linee change to mule-coding.c; if more than twice the amount of odd runs appear than even runs, coding category iso_8_1 is set to `somewhat-likely'. See http://list-archive.xemacs.org/xemacs-beta/200601/msg00083.html This change works and makes auto-detection work for all German files that I tried. (Many of them were not correctly detected before.) The change has not been turned into a patch submission. Would you accept a patch with that change, or would it be dropped?
