Description agctools 2006-11-15 10:12:30 UTC
1. download NetBeans5.5 ml Build 200611150100
2. install JDK 1.5.0_06 on RedHat FC3
3. run nb5.5 installer

1. Some Chinese characters are displayed as squares.

This has impact on Visual Web Pack.

Were there any changes in nb5.5  that might have caused font names
used (jdk font names) different from in past ?
(so that jdk font mapping might not find all needed fonts now ?)

I realize fedora core 3 is not officially supported by jdk
had worked in the past.

The strange thing is that some characters display ok in 
ide and others don't, often in the same line or label.

Comment 4 Ken Frank 2006-11-15 22:52:10 UTC
fedora core is not a supported jdk platform for Chinese (or other asian languages).

  If its worked before then thats been good but using nb5.0
zh_CN installer I see the same situation with boxes.
so am not sure this is a p1 situation in that context.
I communicated with some on jdk team about it, and they confirm
its not supported platform.
see http://java.sun.com/javase/6/docs/technotes/guides/intl/locale.doc.html

I have been experimenting with redhat fontconfig files
and adding some fonts on fc since some mentioned in rh files
are not there on fedora, at least in install am using but seen nothing different
so far.

assuming it is a jdk kind of issue as to font mapping, then
perhaps adding some additional fonts or other workaround with fontconfig
might be found but it would mean users would need to do special actions.

Comment 5 Rebecca Liu 2006-11-16 00:50:43 UTC
Jdk l10n team said Fedora is not officially supported by j2se 1.5.0 and the same
in 6.0. They never did i18n testing on Fedora. Chinese fonts may be ok on RH AS
2.1, 3.0, 4.0. (still cannot be displayed very well) 

That reminds me that we may have the same issue happened in previous releases. I
guess we shall just ignore it and maybe we should add this issue into the
release notes.
Comment 6 Ken Frank 2006-11-16 01:34:10 UTC
Rebecca is correct; I've had other communication with jdk team
and its not supported; i installer nb5.0 zh and also saw the squares.

Am closing this as a result; I do suggest that release notes might
mention this, since FC3 is a supported platform.

Comment 7 Ken Frank 2006-12-05 21:32:39 UTC
release notes have been done that discuss this, approved and also sent to
other packs for their use.
