[Xml-sg-cmt] question: use of <u> element

[Alice Russo <[e-mail]>]

Greetings,

Should the <u> element be used to get the desired output even when it doesn't include the character itself? The <u> can be used to render the "U+" notation or name of a Unicode code point. For example (from draft-faltstrom-unicode12-07):

This output:
 SPHERICAL ANGLE OPENING UP (U+29A1) existed before IDNA2008 was ...

could be rendered w/ this XML:

A)  <t> <u format="name-num">⦡</u> existed before IDNA2008 was ... </t>

instead of 

B)  <t> SPHERICAL ANGLE OPENING UP (U+29A1) existed before IDNA2008 was ...</t>


Should the RPC be using A? 
It would mean a programmatic check (in addition to a manual check) of whether the submitted text is accurate. (i.e., the author submits a long name and "U+" notation, RPC looks it up and puts the actual char in <u> in the source file, renders output, then checks if it matches what was submitted.) 
 
Thanks,
Alice
