Subject: bug#57507: Regular expression matching depends on locale encoding
Date: Wed, 31 Aug 2022 18:54:50 +0200 [thread overview]
Message-ID: <dba30c62-7ac8-21ea-0a79-6a22bb108284@abou-samra.fr> (raw)
Regular expressions do funky things with Unicode if a non-Unicode-aware
locale is set. Yet, they're purely string operations, so I don't think
it's expected that they depend on the locale encoding.
