When I browsed MediaWiki (I was thinking of installing that myself)
http://www.mediawiki.org/wiki/Manual:LocalSettings.php It says on top there:
Warning: Don't edit this file with Notepad or other text editor that adds
byte order marks to files, or you will break your wiki.
I looked into it. You can't edit the MediaWiki php files with regular Notepad because it adds BOM to the file.
So is this a problem when working with all php files?
I found that you can use Notepad++ instead
http://notepad-plus.sourceforge.net/uk/site.htmAfter you install Notepad++
Encoding > Encode in UTF-8 without BOM
(I think that is ok. I am not 100% sure. This stuff is very confusing to me)
What do you guys use ?
