Checked. The limitation is 64 characters. Interestingly, it does allow 
the input of more than 64 characters with the characters remaining 
counter going negative. Don't know how that is handled. Also, the side 
note mentions that IPTC tags have size limitations and advises to use 
xmp instead. Most of my images have the tag information stored in IPTC 
tags. Is there any way I can bulk move all IPTC:Keywords data to xmp? Is 
it really necessary, especially if I can live with the 64 character 
limitation for tags?

Is there a simple way to find out which of my tags are exceeding this 
limit as I am sure there are some? If I can locate them I can truncate 
them to fit the size limitation.
