It's not character case sensitivity/insensitivity case. It's the
"range" problem.
The Czech order of characters is 'AaBbCc...Zz' (i skip the accented
character - for real ordering see src/share/colldef/cs_CZ.ISO8859-2.src)
- it is based on CSN (Czech national normative). It mean, the range
[A-Z] contain both upper and lower letters (with exception of lower 'z'
and accented Zz).
We shall use the '[:upper:]' class instead as nobody knows what the
hell of characters are contained within the X-Y type ranges.
The correct coding for 'awk '/^[_A-Z]/ { print; }'' is 'awk
'/^[_[:upper:]]/ { print; }''. You must be patient with our
english-centristic coleagues - they aren't familiar with existence of
other continents outside of north-america, but they are learning ... ;-)
You should submit a PR (but there are uncountable incarnations of the
same problem in src tree). In the meantime, you should use 'one true
locale' only.
