Subject: [PDFdev] ToUnicode problem
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
>>

(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.
