See "Environment Variables" in the grep manual:
`LC_ALL'
`LC_COLLATE'
`LANG'
These variables specify the locale for the `LC_COLLATE' category,
which determines the collating sequence used to interpret range
expressions like `[a-z]'.
`LC_ALL'
`LC_CTYPE'
`LANG'
These variables specify the locale for the `LC_CTYPE' category,
which determines the type of characters, e.g., which characters
are whitespace.
Your use case would be "fixed" (but it's not a bug, really) by "export
LC_ALL=C".
