|
|
* with the PDFDocEncoding character sequence thorn ydieresis, which is unlikely
|

* to be a meaningful beginning of a word or phrase.) The remainder of the
|
|
* string consists of Unicode character codes, according to the UTF-16 encoding
|
|
* specified in the Unicode standard, version 2.0. Commonly used Unicode values
|
|
* are represented as 2 bytes per character, with the high-order byte appearing first
|
|
* in the string."
|
|
*
|
|
* In other words, if there are chars in a string with char code above 255, we
|
|
* recode the string to UCS2 BE - string doubles in length and BOM is prepended.
|
|
*
|
|
* HOWEVER!
|
|
* Actual *content* (body) text (as opposed to strings used in document properties etc)
|

|
|
*
|
|
* Because of Adobe's focus on "you subset your fonts!" you are not supposed to have
|
|
* a font that maps directly Unicode (UCS2 / UTF16BE) code to font GID, but you could
|
|
* fudge it with "Identity-H" encoding and custom CIDtoGID map that mimics Unicode
|
|
* code page. There, however, all characters in the stream are treated as GIDs,
|
|
* including BOM, which is the reason we need to skip BOM in content text (i.e. that
|
|
* that is tied to a font).
|
|
*
|
