"Well-behaved" almost has to become more narrowly defined than the

<pre class="moz-quote-pre" wrap="">Quite right. I wish I know where the bad idea came from that you're
supposed to accept every technically valid but illegible and

I really like your phrase "Uncritical Acceptance".

<div class="">In a previous email you wrote: "Those issues may require a discussion whether "Universal Acceptance" and "Uncritical Acceptance" are the same thing". (Note - I Title cased for better effect)</div>
<div class=""><br class="">

<div class="">Seeing the two together in a sentence is extremely effective and to me effectively summarises the issues.</div>

<div class="">I consider defining good mailbox naming practices for the whole of Unicode would be a huge undertaking and there would be many overlaps and possibly contradictions with other standards.</div>
<div class=""><br class="">
</div>
<div class="">So, instead, what of defining good mailbox naming practice for just one of the orthography categories? This could serve to illustrate both good practice (Universal Acceptance) and bad practice (Uncritical Acceptance).<br class="">
