Wrong Position of Thai Glyph in FOP 2.0+ (Binary version)

Glyph of Thai Font have problem when start in new line or have white space in front of word.
In Example Wrong.pdf you'll see upper and lower glyph shift to the right 1 character when the base character no have any character before or have white space before.
"อ ิ" the true is should be "อิ"
"อกี" the true is should be "อีก"
"อ ุ" the true is should be "อุ"
"อบุ" the true is should be "อุบ"
remark : Font Angsana New AngsanaUPC , Leelawadee , Norasi and Tahoma are most use in Thai font.

I use Windows command line (cmd) to generate pdf file.
example command line
C:\fop-2.1>fop.bat fop -c conf\fop.xconf -fo wrong.fo wrong.pdf
