Non ascii encoding

Rails
1

Hi guys!

I have a company model with a name attribute. Each company is
association
a set of projects. I created a feature which allows users to
download a csv version of these projects. The download will give you a
zipped file of all projects grouped by company. So the zip file
contains x
number of csv files where x is the number of companies. Everything is
working nice.

But when a user created a company whose name contains greek
characters, I suddenly get issues with encoding. Here’s a small part of
the code that creates the zip file (i’m using zipruby btw)

Zip::Archive.open(file, Zip::CREATE) do |archive|
companies.each do |company|
data = CSV.generate(row_sep: “\r\n”, quote_char: ‘"’, force_quotes:
true) do |csv|
company.projects.each { |project| csv << project.name }
end

archive.add_buffer "#{company.name}.csv", data

end
end

so when company.name contains greek characters, i get a filename similar
to
company???.csv which cant be opened. I can’t find a
way to set the encoding of the filename so I just gsubbed it and ignored
all non-ascii characters which is fine. But if one of the projects also
has a greek character, then the csv file will contain weird non-greek
characters.

Any help or insight is appreciated. Thanks!

Hi Jim,

Looks that you have encoding problems, check your current encoding

puts Encoding.default_external

To solve your problem it should be UTF-8. Because according to the docs

“File http://www.ruby-doc.org/core-1.9.3/File.html data written to
disk
will be transcoded to the default external encoding when written.”

Or you can use additional options :encoding in CSV.generate
(Class: CSV (Ruby 1.9.2))

I checked that out, it is set to utf-8

Encoding.default_external
=> #Encoding:UTF-8

Class: CSV (Ruby 1.9.2)
)

i’ll try this one out but it seems like if i pass the encoding here, all
strings passed will be processed as having that encoding right?
But anyway, it’s the only lead I have so I’ll give it a try. Thanks!
