[Bengali Avro] - Cannot type কষ্ট

Original report on telegram:

Mahmud, [25.07.20 19:26] When I use the "separator" … in this case: I write ক — o as separator — then ষ and ট to make up the word…

Mahmud, [25.07.20 19:26] It ends up glitching the word into ক্ষ্ট instead of কষ্ট।

In the following line:

<pattern input="কশ(h|H)" context="[^o`]" replacement="ক্ষ"/>

We need to replace কশ with ক্শ. The difference between them is that the former is KA + SHA (bug) whereas the latter is KA + VIRAMA + SHA.

We can see this is right by looking at the pattern previous to this:

  <pattern input="ক্ক(h|H)" context="[^o`]" replacement="ক্ষ"/>

Here, KA + VIRAMA + KA + h|H is becoming KSHA
