Mapping files for pre-defined Encodings?

forums_noreply@adobe.com — Wed, 16 Feb 2011 15:26:20 GMT

Hi there,

Does anybody know if and where it is possible to download the PDF pre-defined encodings (StandardEncoding, MacRomanEncoding, WinAnsiEncoding, PdfDocEncoding and MacExpertEncoding) as any processable file?

I found this: http://www.unicode.org/Public/MAPPINGS/VENDORS/ADOBE/ ...but I'm not sure if they are complete and up-to-date.

Furthermore I'm missing a processable file for MacExpertEncoding at all.

Anybody?

Thanks!

MacExpertEncoding mapping file?

forums_noreply@adobe.com — Wed, 16 Feb 2011 14:08:26 GMT

Hi there,

Does anybody know where I can get a mapping-txt file of the "Expert Set and MacExpertEncoding", so we can interpret it automatically?

Thanks!

Encoding of Name Objects

forums_noreply@adobe.com — Thu, 30 Sep 2010 20:16:00 GMT

Hi there!

I just stumbled over a problem I'm not sure how to handle.

It's about handling Name objects with hexadecimal notation.

[...]Regular characters that are outside the range EXCLAMATION MARK(21h) (!) to TILDE (7Eh) (~) should be written using the hexadecimal notation.[...]

No problem with the escape or unescape function but I read further in the PDF specification and found this:

[...]Ordinarily, the bytes making up the name are never treated as text to be presented to a human user or to an application external to a conforming reader. However, occasionally the need arises to treat a name object as text, such as one that represents a font name [...], a colorant name in a separation or DeviceN colour space, or a structure type ([...]).

In such situations, the sequence of bytes (after expansion of NUMBER SIGN sequences, if any) should be interpreted according to UTF-8, a variable-length byte-encoded representation of Unicode in which the printable ASCII characters have the same representations as in ASCII. This enables a name object to represent text virtually in any natural language, [...]

So I understand that a name which is written with/in hexadecimal notation should be interpreted as a UTF-8 byte sequence.

I'd implemented this behaviour already until I reached a real live situation, that clashes with this definition: I created a checkbox form field and define the export value to be "€uro-Wert" (I tried to force this name to UTF-8 notation). Bizarrely Adobe Acrobat (9) encoded the Euro-Sign into PdfDocEncoding. The /AP entry looks like this:

<</D<</Off 42 0 R/#A0uro-Wert 43 0 R>>/N<</Off 39 0 R/#A0uro-Wert 40 0 R>>

I expected:

<</D<</Off 42 0 R/#e2#82#acuro-Wert 43 0 R>>/N<</Off 39 0 R/#e2#82#acuro-Wert 40 0 R>>

So... is this a bug in Acrobat or did I missed something? I mean this Name IS presented to a human through a dialog in Acrobat and also viewable in the form field tree in a panel. So from the view of specification it has to be encoded in UTF-8, or?

Anybody?

Thanks!

Redistribution of Adobe Reader as virtualized Application

forums_noreply@adobe.com — Fri, 18 Jun 2010 09:54:42 GMT

Hi there!

I work for a company that works intensively with creating and modifying PDF documents.

Due to different behaviours on different acrobat (reader) versions, we need to test documents on all of them. Because there's no official way to install different versions on a single machine (or did we missed something?), we think about to virtualize the needed versions.

Some tests showed us, that this works great.

Anyhow we think a step forward: Our customers also want to test PDF documents on different acrobat reader versions. And that's the point: Is it allowed to forward "our" virtualized adobe reader versions to them? Or could we release this files for download on our website? Everything is free of charge, for sure.

Reading the "Reader Distribution License Agreement" I found this term at the end of 2.2(b): "[...]In all cases the Software is to be distributed in complete form and only for purposes of complete installation and use by the end user. The Software shall not be configured or distributed for use without installation.[...]"

...so this agreement says definitely no. But why I could download a virtualized version of adobe reader for month/years from for example xenocode (now spoon): http://spoon.net/AdobeReader ? Do they have a special agreement or did they simply missed something?

It would be great if somebody could bring some light into that issue.

Thank you!

Jan
