Hi, Jakub.  If at all possible, I'd like to request that a back port of 
PR c++/88095 [1] be included in the gcc 9.2 release.

The rationale for including this is that it is required for one of the 
approaches discussed in P1423 [2] (see [3]) that may be useful for some 
programmers to mitigate backward compatibility impact from the adoption 
of char8_t in C++20 via P0482 [4].  Having this feature working in 9.2 
would give impacted programmers more time to evaluate their C++20 
migration options.

The patch has already been integrated in trunk [5].  I verified that it 
applies cleanly against the gcc-9-branch (with the exception of the 
ChangeLog changes), and that tests complete successfully on Linux 
x86_64.  There are no target dependencies involved in this change.

Tom.
