Creation of i18n PDF files (from UTF-8 encoded strings)


#1

Hi,

I have been playing with PDF::Writer for a while, but wasn’t able to
force it to display international characters correctly. I have succeed
to display the right characters using select_font diferencies hash, but
this results to invalid character widths which produced overlapped
texts. I have tried to edit the provided .asf files without any
effect/success.

Any help will be welcome.

Thanks in advance,
Karel

PDF::Writer only supports limited I18N at this point; it will never
support UTF-8 (the underlying specification does not support UTF-8).

When Unicode support is added, it will be using UTF-16.

Austin, thanks for your response.

So is there a chance how to affect the character with by editing the
.asf file?
I mean, I define the in the differences array that 200 will be for
example “Cacute”, but this character is wider than the original one with
ascii code 200.

I have tried editing Helvetica.asf file but without success. It seems
that the PDF::Writer code reading the character widths from .asf is
never executed (due to the conditions).

Any advice concerning this?

Thanks in advance,
Karel
