What does this do?

Im trying to fix two libraries to be compatible with Ruby 1.9 - gruff
and pdf-writer,

and I came accross this:

SyntaxError:
/usr/local/lib/ruby/gems/1.9/gems/gruff-0.3.4/lib/gruff/mini/legend.rb:72:
invalid multibyte char (US-ASCII)
/usr/local/lib/ruby/gems/1.9/gems/gruff-0.3.4/lib/gruff/mini/legend.rb:72:
invalid multibyte char (US-ASCII)
/usr/local/lib/ruby/gems/1.9/gems/gruff-0.3.4/lib/gruff/mini/legend.rb:72:
syntax error, unexpected $end, expecting ':'
...ength < label.to_s.length ? "â¦" : '')

This is the gruff code:

truncated_label + (truncated_label.length < label.to_s.length ? "â^�¦" :
'')

What does a^A do?

I cant even find these on my keyboard let alone find out what they do.

PDF-writer has something similar

/usr/local/lib/ruby/gems/1.9/gems/pdf-writer-1.1.8/lib/pdf/writer.rb:712:
invalid multibyte char (US-ASCII)
/usr/local/lib/ruby/gems/1.9/gems/pdf-writer-1.1.8/lib/pdf/writer.rb:712:
syntax error, unexpected $end, expecting keyword_end
content = "%PDF-#{@version}\n%�¢�£��\n"

Is this hidden Japanese or something?

Thanks,
Petr

It represents Horizontal Ellipsis "=E2=80=A6" =3D=3D "\xE2\x80\xA6" =3D=3D =
"\u2026"

It is just a comment to signal that the file is binary.

Write those with escape sequences.

"\xE2\x80\xA6" and "\xE2\xE3\xCF\xD3"
