Encoding::InvalidByteSequenceError

Raised by Encoding and String methods when the string being transcoded contains a byte invalid for the either the source or target encoding.

Public Instance Methods

destination_encoding → string click to toggle source

Returns the destination encoding as an encoding object.

 
               static VALUE
ecerr_destination_encoding(VALUE self)
{
    return rb_attr_get(self, rb_intern("destination_encoding"));
}
            
destination_encoding_name → string click to toggle source

Returns the destination encoding name as a string.

 
               static VALUE
ecerr_destination_encoding_name(VALUE self)
{
    return rb_attr_get(self, rb_intern("destination_encoding_name"));
}
            
error_bytes → string click to toggle source

Returns the discarded bytes when Encoding::InvalidByteSequenceError occurs.

ec = Encoding::Converter.new("EUC-JP", "ISO-8859-1")
begin
  ec.convert("abc\xA1\xFFdef")
rescue Encoding::InvalidByteSequenceError
  p $!      #=> #<Encoding::InvalidByteSequenceError: "\xA1" followed by "\xFF" on EUC-JP>
  puts $!.error_bytes.dump          #=> "\xA1"
  puts $!.readagain_bytes.dump      #=> "\xFF"
end
 
               static VALUE
ecerr_error_bytes(VALUE self)
{
    return rb_attr_get(self, rb_intern("error_bytes"));
}
            
incomplete_input? → true or false click to toggle source

Returns true if the invalid byte sequence error is caused by premature end of string.

ec = Encoding::Converter.new("EUC-JP", "ISO-8859-1")

begin
  ec.convert("abc\xA1z")
rescue Encoding::InvalidByteSequenceError
  p $!      #=> #<Encoding::InvalidByteSequenceError: "\xA1" followed by "z" on EUC-JP>
  p $!.incomplete_input?    #=> false
end

begin
  ec.convert("abc\xA1")
  ec.finish
rescue Encoding::InvalidByteSequenceError
  p $!      #=> #<Encoding::InvalidByteSequenceError: incomplete "\xA1" on EUC-JP>
  p $!.incomplete_input?    #=> true
end
 
               static VALUE
ecerr_incomplete_input(VALUE self)
{
    return rb_attr_get(self, rb_intern("incomplete_input"));
}
            
readagain_bytes → string click to toggle source

Returns the bytes to be read again when Encoding::InvalidByteSequenceError occurs.

 
               static VALUE
ecerr_readagain_bytes(VALUE self)
{
    return rb_attr_get(self, rb_intern("readagain_bytes"));
}
            
source_encoding → encoding click to toggle source

Returns the source encoding as an encoding object.

Note that the result may not be equal to the source encoding of the encoding converter if the conversion has multiple steps.

ec = Encoding::Converter.new("ISO-8859-1", "EUC-JP") # ISO-8859-1 -> UTF-8 -> EUC-JP
begin
  ec.convert("\xa0") # NO-BREAK SPACE, which is available in UTF-8 but not in EUC-JP.
rescue Encoding::UndefinedConversionError
  p $!.source_encoding              #=> #<Encoding:UTF-8>
  p $!.destination_encoding         #=> #<Encoding:EUC-JP>
  p $!.source_encoding_name         #=> "UTF-8"
  p $!.destination_encoding_name    #=> "EUC-JP"
end
 
               static VALUE
ecerr_source_encoding(VALUE self)
{
    return rb_attr_get(self, rb_intern("source_encoding"));
}
            
source_encoding_name → string click to toggle source

Returns the source encoding name as a string.

 
               static VALUE
ecerr_source_encoding_name(VALUE self)
{
    return rb_attr_get(self, rb_intern("source_encoding_name"));
}
