I had this discussion many times.
<div class="">It is a sort of “general issue”, in the sense that it is a general fact of life. The wider the set, the more likely it is that two elements are “confusingly similar”.</div>
<div class="">If you limit yourself to letter or numbers, the chances for confusion are very limited, or non-existent. However, if you join the two sets, you start having potential confusion.</div>
<div class="">What irritates me is the use of this “potential confusion” as an excuse for not further widening the set joining different scripts.</div>
<div class="">Colors are confusing. The world would be much simpler if we had only black and white. Daltonism would no longer be a problem!</div>
<div class="">Sorry for the rant</div>

Hello David,
<div class=""><br class="">
</div>
<div class="">Were pairs like 1 and l , 0 and o in latin script analyzed?</div>
<div class="">(it might give better perception of what it going on and if the confusion is limited to IDNs or is it a general issue)</div>
