[charmod-norm] Does ZWJ/ZWNJ affect meaning?

r12a has just created a new issue for 

== Does ZWJ/ZWNJ affect meaning? ==
section 2.4 of the document[1] says

"A special case are the Unicode control characters U+200D Zero Width 
Joiner (also known as ZWJ) and U+200C Zero Width Non-Joiner (also 
known as ZWNJ). These invisible controls sometimes do affect the 
meaning of characters sequences where they appear, although their 
usual use is to control ligature formation— either preventing the 
formation of undesirable ligatures or encouraging the formation for 
desirable ones."

is this correct, ie. that the presence of ZWJ or ZWNJ can actually 
change the meaning of the text. If so, do we have an example?
