           Summary: [bn][bn-IN][as] Invalid addition of Yaphala conjuncts
                    are being rendered
           Product: Fedora
           Version: rawhide
          Platform: All
        OS/Version: Linux
            Status: NEW

          Severity: medium
          Priority: low

    Classification: Fedora
    Target Release: ---


Description of problem:

In case of conjuncts with Yaphala (U09CD+U09AF), multiple Yaphala signs can be
typed consecutively giving rise to invalid conjunct combinations. 

e.g ক্য্য্য্য (ক+্+য+্+য+্+য+্+য)

This error could be replicated in gedit, kwrite and Openoffice.org Writer


Version-Release number of selected component (if applicable):

fonts-indic: 2.3.8-1.fc11
gedit : 2.26.1-1.fc11
openoffice.org: 3.1.0-9.2.fc11
kdebase : 4.2.2-2.fc11


How reproducible:


Steps to Reproduce:
1. Open gedit
2. Type in the following unicode values (for the above example) :

U0995+U09CD+U09AF+U09CD+U09AF+U09CD+U09AF+U09CD+U09AF

Actual results:

The last 3 U09CD+U09AF pairs are allowed as part of the conjunct

Expected results:

The U09CD+U09AF pair should not be allowed to be rendered after another
U09CD+U09AF. i.e. only one U09CD+U09AF pair can be used when combining with
another consonant to form a conjunct.

Additional info:

Please do note that: U09AF+U09CD+U09AF is a valid conjunct combination, where
two U09AF characters combine to form a conjunct (য্য)
