What does this do?


#1

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 ? “⦔ : ‘’)

This is the gruff code:

truncated_label + (truncated_label.length < label.to_s.length ? “â^À¦” :
‘’)

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%âãÃÃ\n”

Is this hidden Japanese or something?

Thanks,
Petr

Also Transaction Simple makes this error:

no marshal_dump is defined for class Mutex

/usr/local/lib/ruby/gems/1.9/gems/transaction-simple-1.4.0/lib/transaction/simple.rb:129:in
dump' /usr/local/lib/ruby/gems/1.9/gems/transaction-simple-1.4.0/lib/transaction/simple.rb:129:instart_transaction’

start_transaction' /usr/local/lib/ruby/gems/1.9/gems/pdf-writer-1.1.8/lib/pdf/simpletable.rb:396:inrender_on’

ANy ideas?

What does a^A do?

It represents Horizontal Ellipsis “…” == “\xE2\x80\xA6” == “\u2026”

Is this hidden Japanese or something?

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”
