We have a project in Burmese project that has Zero Width Non-Joiner (u+200C) invisible characters which I would like to mark as Invalid in the Characters inventory, but we cannot. We get a message:
However it does not exist in the Alphabetic Characters tab.or any other tab of the Language settings.
I also found the the same was true for Zero Width Joiner (u+200D).
When I examined the ldml.xml file and found these curious lines:
<!--sil:punctuation-pattern pattern="" context="medial" /-->
<sil:punctuation-pattern pattern="" context="medial" />
Inside the quotes were the ZWNJ 200C and ZWJ 200D characters. I tried deleting these lines but that did not change Paratext’s behavior.
I also did an experiment in an English project and tried adding ZWNJ and ZWJ to the language settings. Even though they were added as non-standard diacritics, I was not able to see them in the character inventory.
So I am wondering is this a feature or a Bug? Is the behavior of ZWNJ and ZWJ built into the behavior of certain languages and cannot be changed? If not, how can I mark ZWNJ Invalid in my Burmese project? (Note: The language code for Burmese is my.)
