[Devel] Re: strange cmap syntax

[Ken Lunde]

Werner,

Acrobat ships with many CMap-like files. That is, they look like CMap 
files, and even use CMap file syntax. They are not, however, CMap files. 
This particular one maps 90pv-RKSJ-H code points (Shift-JIS) to Unicode. 
In the third column, each four hex digits represent a Unicode code point. 
Thus 90pv-RKSJ-H 0x8591 maps to U+0030 plus U+002E.
