I always thought 昭 could be pronounced as ciu1 or ziu1.
Are you sure you’ve ever heard anyone pronouncing 昭 as ziu1?
Despite the listing of ziu1 as variant reading of ciu1 on CUHK site and 粵語拼音字表, I haven’t heard of anyone using the ziu1 reading during the past few decades. Newer dictionary 廣州話正音字典 gives only one reading ciu1.
But I don’t object to adding ziu1 as variant reading if any other editor would like to do so.
