FULL PRODUCT VERSION :
Reproducible with 1.4.2 also
java version "1.5.0-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-beta-b32c)
Java HotSpot(TM) Client VM (build 1.5.0-beta-b32c, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows 2000 [Version 5.00.2195]

A DESCRIPTION OF THE PROBLEM :
I have created a text editor using JTextPane. I have set the StyledDocument as
the DefaultStyledDocument. If I use some locale specific fontname suitable for
multibyte characters, say a fontname which contains Japanese language
characters , to format the text , on reopening the editor, the font name
information is lost.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1.Create a JTextPane and attach a DefaultStyledDocument to it.
2.Create a RTFEditorKit and set some rtf text on JTextPane.
3.Use the read/write API's of RTFEditorKit and write this DefaultStyledDocument into RTF2.rtf file.
4. Compare the original rtf text set on textpane with RTF2.rtf.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The rtf generated should be same as the rtf set on the JTextPane.
ACTUAL -
Both rtfs are different.

REPRODUCIBILITY :
This bug can be reproduced always.
