<i18n dev> [13] RFR 8209175: Handle 'B' character introduced in CLDR 33 JDK update for Burmese (my) locale

[Nishit Jain]

Hi,

Please review the fix for JDK-8209175

Bug: https://bugs.openjdk.java.net/browse/JDK-8209175
Webrev: http://cr.openjdk.java.net/~nishjain/8209175/webrev.03/


Issue: In CLDR 33 update, 'B' character has been added in date time 
patterns for Burmese locale, which is used to represent the day period. 
This character is not supported in DateTimeFormatter or SimpleDateFormat 
APIs, so an exception is thrown that an "unknown character is encountered"

Fix: A workaround is added in which 'B' character appearing in CLDR 
date-time pattern is replaced with 'a' character and hence resolved with 
am/pm strings. This is based on the LDML specification given for 'B' 
character in which it falls back to 'a' character if it is not supported 
by any locale.


Regards,
Nishit Jain
