I\'m new to Cygwin, I just installed it and attempted to set some simple environment variables. However, when I open the command shell, I get the error \"#357\\273\\277 com
As far as I know, a common problem with files saved in Notepad++ as UTF-8 and Cygwin is that Notepad++ saves UTF-8 encoded files with a byte order mark by default. This BOM character is not quite compatible with unix-like environments like Cygwin.
If you need unicode characters in these files, then you can try using the "UTF-8 without BOM" encoding in Notepad++, otherwise you can use ANSI or other encodings that don't use a BOM by default.
Besides the encoding, make sure the file's saved with unix (LF) line-breaks.
