That might be the case, but LWG wanted changes before they were willing to merge it, hence my message.

Hi all,


I think Jeff’s proposed wording adequately resolves the NB comment.

Hello Jeff and SG16.


In LWG today there were 4 concerns raised:

  1. Historic => historical
  2. Missing :: in the u8path reference
  3. ISO rules forbid ‘should’ in notes.
  4. The ‘should in new code’ form is somewhat ‘preachy’ and we should say why.


To those ends, how about this:


[Note: The example above is representative of a historical use of filesystem::u8path. Passing a std::u8string to path’s constructor is preferred for an indication of UTF-8 encoding more consistent with path’s handling of other encodings. -- end note.]
