My 2 c: If pcregrep supported 16-bit, yes it should accept 8-bit
patterns and file names in 16-bit mode to allow grep requests to be run
at the command line. But since stdin is not unicode, input data would
need to come from other files. Without special coaxing the CMD console
will not display unicode, so in a CMD console window, user would likely
redirect to a file (which I suppose should get a BOM?) for viewing
elsewhere. But if using a PowerShell console window, viewing results in
the console window might work.

If you want Windows users to run any tests on the preliminary work
that's already done for 16-bit, you should update the cmake files and
run the PrepareRelease script. Maybe you could name test versions "PT"
instead of "RC" for "preliminary test".

Here are some interesting links about the Windows console:
