Re: odd behavior of length(), match() and field splitting with multi-byte characters

[Ed Morton]

FWIW I also can't reproduce the issues with gawk 4.2.1 on Linux but can 
with gawk 5.0.0 on git bash on Windows (which is obviously cygwin-y if 
not identical).

Do the cygwin port maintainers read this mail archive or do I need to do 
something different to contact them?
