Thanks Vyom. You could have proposed the patch yourself only...
Anyways, I have tested with Font2DTest with all unicodes for default
Latin and it seems ok. Will you be able to test in other CJK locales
(as I am not sure of the unicodes being displayed correctly) just to
ensure they are not adversely affected?
Any feedback on CJK locale testing with your fix? If not, I am afraid we
need to retarget this fix for jdk16.

Hi prasanta,
Code changes look OK to me, although I am not a expert in this area,
but the same patch resolves the issue at our end.
Thanks,

Hi All,
Please review a fix for an issue seen whereby RTFEditorKit used
to read Japanese characters reads some garbage characters.
The default character set used for the RTF document is set to
"ansi" in our RTFReader.java.
And share/classes/javax/swing/text/rtf/charsets/ansi.txt code
table has undefined values , i.e., 91-98 and A0 are "0".
According to javax/swing/text/rtf/RTFParser.java, If the ch is 0,
handleText() is not called
As per http://www.biblioscape.com/rtf15_spec.htm#Heading8,
/RTF file includes the following Character set in its header : //
//<character set> //
// (\ansi | \mac | \pc | \pca)? \ansicpgN? //
//Where, //
//\ansicpgN This keyword represents the default ANSI code page
used to perform the *Unicode to ANSI conversion* when writing RTF
text. N represents the code page in decimal. This is typically
set to the default ANSI code page of the run-time environment
(for example, \ansicpg1252 for U.S. Windows). The reader can use
the same ANSI code page to convert ANSI text back to Unicode.
This keyword should be emitted in the RTF header section right
after the \ansi, \mac, \pc or \pca keyword. /
Possible values include those in the following table.We can make
use of ansicpgN (can switch ANSI text to Unicode), define it to
refer to the latin1TranslationTable [RTFParser inherits it from
AbstractFilter] which does not include undefined areas instead of
ansi's translationTable which has undefined areas as seen above.
Bug: https://bugs.openjdk.java.net/browse/JDK-8244324
webrev: http://cr.openjdk.java.net/~psadhukhan/8244324/webrev.0/
Note: I am not able to create a testcase for this as it involves
reading from rtf file which probably is copyrighted and inserting
Japanese characters as a string (instead of rtf file) was not
working.
