[PDFdev] ToUnicode problem

[Peter Persits]

Hi all,

 

I wandering if someone could shed some light.

 

My application generates PDF files with embedded TrueType fonts, and enables non-ASCII alphabets through Type0 fonts with Identity-H encoding and Unicode-to-glyph-ID conversion. Everything works great, Hebrew and Russian words display just fine, but copying/pasting these words to other apps (such as MS Word) does not work...

 

So I attempted to add a ToUnicode entry to my Type0 fonts... Now the Reader completely disables highlighting of text, and spews out the message "The encoding (CMap) specified by a font is corrupt". Here is what it looks like:

 

7 0 obj
<</Type /Font
/Subtype /Type0
/BaseFont /Arial
/Encoding /Identity-H
/DescendantFonts [8 0 R]
/ToUnicode 12 0 R
>>
endobj

 

 

12 0 obj
<</Length 685
>>
stream
/CIDInit /ProcSet findresource begin
12 dict begin
begincmap
/CIDSystemInfo
<< /Registry (Adobe)
 /Ordering (UCS)
 /Supplement 0
>> def
/CMapName /Adobe-Identity-UCS def
/CMapType 2 def

endcodespacerange

<026d> <026d> <0443>
<0271> <0271> <0447>
<0275> <0275> <044b>
endbfrange
endcmap
CMapName currentdict /CMap defineresource pop
end
end
endstream
endobj

 

 

(I currently have a separate entry for each character in the text being displayed, will change it later to ranges). Can anyone spot any abnormalities with this?

 

Thanks a lot in advance.
