vim: dbext output unreadable - vim

Question

I'm running: Windows 7, gvim 7.4
Put this in my vimrc:
"------------dbext--------------
" Microsoft SQL Server
let g:dbext_default_profile_microsoft_production = 'type=SQLSRV:integratedlogin=1:dsnname=SQLOLEDB.1:srvname=SVR:extra=-t'
Tried it with and without the "extra=-t" with the same result:
Here is my entire vimrc:

Answer 1

The leading ÿþ characters give it away; that's a byte order mark (hexadecimal 0xFFFE), used for 16-bit Unicode encodings. Vim didn't properly detect that. Read :help 'fileencodings' to learn how to fix that, or just (re-)read the buffer via
