Subject Re: FOP 1.1 - Japanese 4-byte characters are rendering as '?' in pdf
Date Wed, 20 May 2015 13:21:21 GMT
Firstly, I suggest you avoid using the term "4-byte Japanese characters",
since that has no meaning except in the context of some encoding, like
UTF-8, UTF-16, UTF-32, etc. In Java, all String objects are encoded in
UTF-16 as 16-bit code units. So BMP characters use one 16-bit code unit,
and non-BMP characters use two 16-bit code units, i.e., an upper and lower

Hiragana characters are encoded in the BMP in the range U+3040 to U+309F
[1], Katakana in U+30A0 to U+30FF [2], and CJK Ideographs starting at

[1] http://www.unicode.org/charts/PDF/U3040.pdf
[2] http://www.unicode.org/charts/PDF/U30A0.pdf
[3] http://www.unicode.org/charts/PDF/U4E00.pdf

For external FO files, or XML files you will translate to FO via XSLT, you
should use the UTF-8 encoding of Unicode, and ensure that you provide a
correct XML declaration at the beginning of your file:

<?xml version="1.0" encoding="utf-8"?>

I also suggest that you ensure the presence of the UTF-8 encoding of the
BOM [4] at the beginning of the file: 0xEF 0xBB 0xBF.
