Hello,
Could you review a fix for jdk8u, please?
bug: https://bugs.openjdk.java.net/browse/JDK-8201801
webrev: http://cr.openjdk.java.net/~dmarkov/8201801/jdk8u/webrev.00/
Problem description:
The fix for 7162125 [1] enabled font tables processing on OSX. However there is
a lack of support for RTL languages in ICU layout engine. Quote from ICU guide:
“…The AAT processing in the LayoutEngine is relatively basic as it only applies
the default features in left-to-right text. This processing has been tested for
Devanagari text. Since AAT processing is not script-specific, it might not work
for other scripts…”, more details at
http://userguide.icu-project.org/layoutengine
As a result all RTL languages on OSX are incorrectly laid out, (i.e. the
letters are reversely presented).
Fix:
Skip font tables for RTL languages on OSX platform.
Thanks,
Dmitry
