The parser works in the Encoding of the IO ;TI"Tor String object being read from or written to. Your data is never transcoded ;TI"S(unless you ask Ruby to transcode it for you) and will literally be parsed in ;TI"Sthe Encoding it is in. Thus CSV will return Arrays or Rows of Strings in the ;TI"SEncoding of your data. This is accomplished by transcoding the parser itself ;TI"into your Encoding.;T@o; ;[I"SSome transcoding must take place, of course, to accomplish this multiencoding ;TI"Fsupport. For example, :col_sep, :row_sep, and ;TI"Q:quote_char must be transcoded to match your data. Hopefully this ;TI"Qmakes the entire process feel transparent, since CSV's defaults should just ;TI"Rmagically work for your data. However, you can set these values manually in ;TI"2the target Encoding to avoid the translation.;T@o; ;[I"LIt's also important to note that while all of CSV's core parser is now ;TI"JEncoding agnostic, some features are not. For example, the built-in ;TI"Oconverters will try to transcode data to UTF-8 before making conversions. ;TI"RAgain, you can provide custom converters that are aware of your Encodings to ;TI"Javoid this translation. It's just too hard for me to support native ;TI",conversions in all of Ruby's Encodings.;T@o; ;[ I"TAnyway, the practical side of this is simple: make sure IO and String objects ;TI"Spassed into CSV have the proper Encoding set and everything should just work. ;TI"QCSV methods that allow you to open IO objects (CSV::foreach(), CSV::open(), ;TI"MCSV::read(), and CSV::readlines()) do allow you to specify the Encoding.;T@o; ;[ I"ROne minor exception comes when generating CSV into a String with an Encoding ;TI"Othat is not ASCII compatible. There's no existing data for CSV to use to ;TI"Tprepare itself and thus you will probably need to manually specify the desired ;TI"SEncoding for most of those cases. It will try to guess using the fields in a ;TI"Mrow of output though, when using CSV::generate_line() or Array#to_csv().;T@o; ;[I"RI try to point out any other Encoding issues in the documentation of methods ;TI"as they come up.;T@o; ;[ I"SThis has been tested to the best of my ability with all non-"dummy" Encodings ;TI"MRuby ships with. However, it is brave new code and may have some bugs. ;TI"SPlease feel free to {report}[mailto:james@grayproductions.net] any issues you ;TI"find with it.;T: @fileI"lib/csv.rb;T:0@omit_headings_from_table_of_contents_below0;0;0[[ I"col_sep;TI"R;T:publicFI"lib/csv.rb;T[ I" encoding;TI"R;T;F@�[ I"field_size_limit;TI"R;T;F@�[ I"lineno;TI"R;T;F@�[ I"quote_char;TI"R;T;F@�[ I"row_sep;TI"R;T;F@�[ I"skip_lines;TI"R;T;F@�[ U:RDoc::Constant[iI"VERSION;FI"CSV::VERSION;T00o;;[o; ;[I"*The version of the installed library.;T;@�;0@�@cRDoc::NormalClass0U;[iI"FieldInfo;FI"CSV::FieldInfo;T00o;;[o; ;[ I"NA FieldInfo Struct contains details about a field's position in the data ;TI"Rsource it was read from.
