Rake aborted! Invalid byte sequence in UTF-8 - ruby-on-rails

This problem has been plaguing me for hours! When trying to precompile my assets on the AWS instance, I get the following:

Tasks: TOP => assets:precompile
I am running ruby 1.9.3p327 (2012-11-10 revision 37606) [x86_64-linux]

I solved the issue by doing the following:
$ cd opt/bitnami/ruby/lib/ruby/gems/1.9.1/gems/hike-1.2.3/lib/hike
$ sudo chmod 777 index.rb
$ sudo vim index.rb
Then, insert (press letter i on keyboard): # encoding: utf-8 before first line.
Hit esc and then type :wq then press enter to save.
After, put permissions back for index.rb by doing the following
$ sudo chmod 644 index.rb
Hope this helps someone in the future.

In case anybody else comes across this question, while Tomanow's answer didn't quite work for me, I discovered there were offending characters in my file, which is what caused this issue.
The files, which came from Open Layers version 2.13, contained a copyright symbol in the comments section of some of their javascript and css files. Anybody else having a similar issue could also attempt to look for and remove those characters, if that's a feasible. Check out this answer for more details.

In my case the issue was happening on every rake task. I found out that it was due to the presence of some files with odd names that were accidentally created on the app's main directory, such as "?," and "\342,". Everything worked fine after I removed them.

I found the solution: it turns out that the internal asset cache in sprockets gem somehow got corrupted file names and as a result the link to the actual image file was causing an exception. Use the following application config setting to flush the cache and overcome this: # Version of your assets, change this if you want to expire all your assets config.assets.version = 'v.2'

Error with heroku run rake db:migrate - Errno::ENOENT: No such file or directory - /app/db/schema.rb

I was trying to get my project working on Heroku but when I was trying to run "rake db:migrate" got the following
any idea????
Thanks :)
P.D: I think the probles is here
** Execute db:schema:dump
rake aborted!
Because
Rake tasks that write to disk, such as rake db:schema:dump, are not compatible with Heroku’s ephemeral filesystem.

Tasks: TOP => db:schema:dump
Do you not have a db/schema.rb file in your application? That file should be in ApplicationName/db/schema.rb If this is your first upload to heroku maybe try to run rake db:seed first to create the schema file, then do your migrations after.
The problem was Windows...
Windows rename the /db folder as /DB, and heroku breaks if this happens.

rake assets:precompile fails – file exists

I've stumbled onto a bit of a weird issue with my Rails app...
Until recently, my app has been running fine. Now, when trying to precompile assets, I'm getting a 'rake aborted!' error.
Even though I've removed all assets, I'm getting a File exists error...
My-MacBook-Pro-2:myapp myname$ ls public/assets
ls: public/assets: No such file or directory

Tasks: TOP => assets:precompile
My-MacBook-Pro-2:myapp myname$
I've tried removing the public/assets directory manually, using rm -rf public/assets, and, I've also ran rake assets:clean successfully – and the issue is still not resolved.
I'm trying to pinpoint what could cause the issue. Any help is appreciated!
I ended up resolving this issue –
Due to the lack of specificity in the error log, it was difficult to pinpoint. The issue was, in my /fonts directory, I had a file named 'myapp'... with no suffix... this caused Rails to puke.

How to use asset names involving Unicode?

I have a number of audio file names that I need to support which are written in Chinese romanization, for example wǒ shì xuésheng.mp3. There seems to be a problem translating these into asset paths or handling the resulting paths, as
http://localhost:3000/assets/wǒ shì xuésheng.mp3
http://localhost:3000/assets/w%C7%92+sh%C3%AC+xu%C3%A9sheng.mp3
http://localhost:3000/assets/w%C7%92%20sh%C3%AC%20xu%C3%A9sheng.mp3
Don't result in anything. I tried asset_path and Rack encode, but there seems to be no way to access these files that are in my directory structure. In order to eliminate potential error sources, I also tried with a file named ma ma.mp3 in the same directory and that one loads fine, so the problem seems to be with the Unicode characters in the file names.
Funnily enough, File.exists works:
File.exists?(File.join(Rails.root, "/app/assets/audios/", "wǒ shì xuésheng.mp3"))
Also, European diacritics work:
http://localhost:3000/assets/bù.mp3
Just Unicode ones break the system.
I'm using Rails 3.2.11 and Ruby 1.9.3. (EDIT: this issue persists even in Rails 4.0.2)
EDIT: I suspect it's a problem with the asset pipeline because I also cannot do a rake assets:precompile while I have Unicode characters in a filename, it fails with "undefined method directory? for nil:NilClass".
EDIT: this is the trace for rake assets:precompile:

Tasks: TOP => assets:precompile
There've been a large number of bug fixes in the Rails 3.2.x patch releases that may have addressed this issue. Other posts here have implied that upgrading to 3.2.14 fixes this UTF-8 URL encoding issue.
I recommend upgrading to Rails 3.2.15 (current patch release) to see if this issue is resolved.
This is a problem with different handling of Unicode filenames on Windows, Mac and Linux. I tried running the same code on a friend's Linux computer and the same code runs perfectly there.
Since File.exists? works but the asset-related code doesn't, I believe that the asset-related code has not been written from a platform-independent point of view, while the File utilities have. I'm submitting a bug report.

Hi when I am running rake command it is ending up with "Error: Out of stack space".

I don't know the error but gotta know that it is a windows specific error.I have copied the same application and did rake command in ubuntu and worked well.
I'm getting the same response when I try to precompile using the ckeditor gem. The init.js.erb includes other JS files, some of which are already 'compressed' and as a result, the file is essentially one big string of text without any line breaks. If I open it in Komodoedit I get a warning saying the info is truncated because it is too long. Perhaps this is what is happening when Uglifier tries to read and then compress the string data. I don't know of a solution as it only just recently happened to me. Use rake assets:precompile --trace to see where the error actually crops up.
