问题
A Sprockets::EncodingError exception is thrown when I include a file with characters that are valid utf-8.
The line in question is:
* Copyright (c) 2010 - 2011 Johan Säll Larsson
If I replace the ä character, the problem goes away, but I don't want to have to remember to edit this vendor file everytime I update it.
How can I fix this?
回答1:
I found the solution via the comments on this Sprockets issue:
I simply saved the file as utf-8, (TextMate has an option to do this when you chose 'Save As'), and the problem went away.
The commenter @shedd also created a useful rake task to find assets which are not encoded properly.
回答2:
This is fixed in trunk. All files use utf-8 without BOM.
