invalid byte sequence in UTF-8 #35

Open mrrooijen opened 11 years ago

mrrooijen commented 11 years ago

Hi there,

I came across your gem and figured I'd give it a go. Unfortunately whenever I add your gem along with your buildpack, it always results in the following error:

-----> Preparing app for Rails asset pipeline
       Running: rake assets:precompile
       rake aborted!
       invalid byte sequence in UTF-8
       Tasks: TOP => assets:precompile:all
       (See full trace by running task with --trace)
       Precompiling assets failed, enabling runtime asset compilation
       Injecting rails31_enable_runtime_asset_compilation
       Please see this article for troubleshooting help:
       http://devcenter.heroku.com/articles/rails31_heroku_cedar#troubleshooting

It seems to have finished compiling the assets though, and it finishes the deployment and the assets work on the application itself. However, I think there might be some turbo-sprockets-related post-processing that might be failing.

When I remove the gem and the buildpack, the application's assets compile just fine. When I re-add the gem and buildpack, the same error occurs again.

Do you have any idea why this is happening? The applicatie is very Javascript heavy so I think it'd benefit greatly from your tool.

Thanks!

I'm seeing the same issue when deploying with Capistrano (Rails 3.2.8):

(I believe the iconv deprecation warning is unrelated, I believe. It's from the rubyjedi-soap4r gem.)

Here's my assets group:

group :assets do
  gem 'sass-rails',     '~> 3.2.3'
  gem 'bootstrap-sass', '~> 2.1.0.0'
  gem 'handlebars_assets'

  # See https://github.com/sstephenson/execjs#readme for more supported runtimes
  gem 'therubyracer', :platforms => :ruby

  gem 'uglifier', '>= 1.0.3'

  gem 'jquery-ui-rails'
end

I hope that's helpful.

Also just started seeing this after updating to rails 3.2.10 and the 0.3.0 line of this gem. Also hit the same error with MRI.

I'm getting this error as well...Rails 3.2.11.

A little more info...I found that this error is popping up while processing the Modernizr javascript asset--which I've included into my app with:

gem "modernizr", "~> 2.6.2"
ngan commented 11 years ago

It appears that where the error being raised isn't the real problem. The file that it was trying to process was: public/assets/modernizr/emoji-1fdffd9da5acbc887bfa5226a3ba6a43.js which has some mangled UTF-8 characters. The original file provided by the gem is read and worked with just fine. So I'm thinking that whatever is writing the file public/assets/modernizr/emoji-1fdffd9da5acbc887bfa5226a3ba6a43.js is messing it up.

Original file:

//= require modernizr
// Requires a Modernizr build with `canvastext` included
// http://www.modernizr.com/download/#-canvas-canvastext
Modernizr.addTest('emoji', function() {
  if (!Modernizr.canvastext) return false;
  var node = document.createElement('canvas'),
      ctx = node.getContext('2d');
  ctx.textBaseline = 'top';
  ctx.font = '32px Arial';
  ctx.fillText('\ud83d\ude03', 0, 0); // "smiling face with open mouth" emoji
  return ctx.getImageData(16, 16, 1, 1).data[0] !== 0;
});

Compiled file (cat to console):

// ...
t.fillText("??????",0,0),t.getImageData(16,16,1,1).data[0]!==0});

any updates on this? we'd love to use this gem, and so far it looks great, but this kind of potential issues makes us a little scared

gingerlime commented 11 years ago

We were doing fine so far, but suddenly started seeing a similar error when deploying (however it complains about US-ASCII instead of UTF-8. Would be great if anyone has some workarounds / solutions / ideas on this...

gingerlime commented 11 years ago

Sorry, false alarm. This is (most likely) not the same issue. I think I found a fix for this particular problem: https://github.com/fnando/i18n-js/pull/139

jakswa commented 11 years ago

+1 for having this issue as well. steverandy's modification fixes things (#64), but it seems like it's not a good approach to the issue? any other ideas on this? It seems really hard to pinpoint what causes this error if you are adding it to a project for the first time (and there are many asset files that could be the culprit...).

stereoscott commented 11 years ago

Check out our findings over in this comment: https://github.com/ndbroadbent/turbo-sprockets-rails3/pull/64#issuecomment-18654913. In my case I was getting this error when turbo-sprockets was reading a file that had been run through the default sprockets--> uglifier chain. Uglifier was converting ascii versions of the unicode characters in my source js into UTF-8, which when read back into turbo-sprockets will read as an invalid byte-sequence. Setting uglifier to ascii_only in your app's production.rb seems to fix the issue.

elskwid commented 11 years ago

Following on from @ngan's comments I too had some problems with Modernizr.

GBH commented 10 years ago

Maybe this is relevant? https://github.com/intridea/multi_json/issues/136

rap1ds commented 10 years ago

+1 Same issue here. This is preventing me from using this gem :(
