Hey I am really enjoying using emacs, but i have found an error that makes my work flow a little slower. I have tested the issue on the version 23.1.1 on a windows xp, have also found the problem in 22.2.1 First i recognized the problem, when I used AUCtex and from emacs called an external pdf-viewer called sumatraPDF. SumatraPDF then saved its settings in c:/Documents and Settings/Jonas B'klund/Applikation Data But my user on the system is "Jonas Bęklund", so the call from emacs have changed the danish letter ę to ' . When I called the pdf-viewer directly from windows or from the commandspromt it saved its settings in the correct folder. Playing around with emacs and sumatraPDF, I found that it is with nearly 100% certainty isn't sumatraPDF that is the problem: The reason is that I tried to run emacs on my desktop, it starts up nicely, but when I tried to open the internal Top Level Customization Group, it reported the following error: defconst: Cannot open doc string file "c:/Documents and Settings/Jonas B\346klund/Skrivebord/emacs-23.1/lisp/wid-edit.elc" Here it should be said that Skrivebord is the danish word for Desktop. So it seems that there is some error in the encoding of the username/ folder name in emacs, that have changed ę to \346 Hope you can find some solution, since it could be nice to get rid of this extra "user" when using emacs with sumatraPDF. /Jonas Bęklund
