Patch for scramble of PDF properties in UTF-8 environment
Thank you for the development of such a great product!
For PDF properties (such as Title, Author, and else), the encoding
of multi-byte characters should be UTF-16BE with BOM prefix, not UTF-8.
Below is a patch for this problem. The patch will provide
method overridings of SetTitle() and textstring(),
which are original in vendor/plugins/rfpdf/lib/rfpdf/fpdf.rb.
I have checked this patch in Japanese environment (see attached images),
but I suppose it should be applicable to other multi-byte environments
(such as Chinese, Korean, and so on) encoded by UTF-8.
Thank you for your consideration in advance.
