Hi SG16,

I'd like you to take on CWG issue #1871:

1871. Non-identifier characters in ud-suffix

Section: 5.13.8  [lex.ext]     Status: extension     Submitter: Richard Smith     Date: 2014-02-17

(From messages 24712 through 24714, 24716, 24717, and 24719.)

A ud-suffix is defined in 5.13.8 [lex.ext] as an identifier. This prevents plausible user-defined literals for currency symbols, which are not categorized as identifier characters.

Rationale (June, 2014):

CWG felt that a decision on whether to allow this capability or not should be considered by EWG.

Please let EWG know what you think, given the ongoing TR31 work. EWG will then discuss your proposal, hopefully adopting it as-is, and forward to CWG.

Sounds good.  I filed an SG16 issue (https://github.com/sg16-unicode/sg16/issues/61) to ensure we follow up on this.  We'll discuss at an upcoming telecon.

SG16 discussed this at our April 22nd, 2020 telecon.

The following poll was performed:

Poll: Is there any objection to unanimous consent for recommending rejection of this proposal?
- No objection to unanimous consent.

So, SG16 consensus is (so far) unanimous to reject this issue.  Per our operating procedures, objections to the consensus can be raised over the next week (I just posted notification of the poll today), but I'm not anticipating any.  I advise EWG to proceed with this recommendation at its leisure.

Tom.
