I don't have time to try the following "locale" fix right now but in
case others have that weirdness with case insensitivity in grep, this
tip may help:

A comment to "bug #30327: regex ranges [A-Z] and [a-z] ignore case"
says the following:

"Not a bug, but a function of your current locale. For more details,
see FAQ E9 in the bash FAQ:

"Either set LC_ALL=C in your environment (technically, LC_COLLATE=C is
sufficient, but then you have to guarantee that LC_CTYPE is
compatible), or use [[:upper:]] and [[:lower:]] instead of [A-Z] and
[a-z] for proper locale case-sensitive regexes in your current

Meanwhile I installed agrep as an alternative grep tool. Agrep does
case sensitivity as expected without any changes to "locale." I'll
look into "locale" settings later.
