From f57584ac73f870dee1a3bd48d5ad6d7d1e7e6ea4 Mon Sep 17 00:00:00 2001 From: Eshel Yaron Date: Wed, 10 Apr 2024 19:34:53 +0200 Subject: [PATCH] FIXED: workaround Emacs incompatibility with certain locales The Emacs Elisp reader only works with locales that have "." as their decimal separator, but Prolog initialization sets up the locale according to the environment variables. Therefore we need to reset the locale after initializing Prolog in case the environment prescribes a locale with a different decimal separator, such as fr_FR.
