ruby - Rails Error: "\xE4" followed by "l" on UTF-8 -

-

when load css or js files on rails 4.2.6 link tags javascript_include_tag , stylesheet_link_tag error:

encoding::invalidbytesequenceerror @ /app "\xe4" followed "l" on utf-8

i never saw error before. , when load these same files html script like:

<script src="/assets/app/functions.js"></script>

then works.

my app/assets/javascripts/application.js is:

//= require jquery //= require jquery_ujs //= require turbolink__s edited //= require__tree .  edited

someone had problem before?

thanks!

ok, since not seem understand short explanation in comments, put answer.

puts "\xe4".force_encoding('iso-8859-1').encode('utf-8') #⇒ ä

that said, either 1 (or many) of stylesheets, or 1 (or many) of javascripts stored in iso-8859-1 encoding. ruby tries read in utf-8 default. should find file causes problems, open in editor , save in utf-8 encoding.

you might bulk update smth like

dir['*/**/*.js', '*/**/*.css'].each |f|   file.write f, file.read(f).force_encoding('iso-8859-1').encode('utf-8') end

please aware bulk update might cause opposite problem, if of files contained valid utf-8.
