        <pre>This is because since r201066 JSC also uses the preferred language from the system locale instead of falling back to &quot;en&quot; and those tests expect the locale to be en_US. run-javascriptcore-tests does $ENV{LANG}=&quot;en_US.UTF-8&quot;; but we are not actually honoring the environment variables at all when using jsc binary. We are using setlocale with a nullptr locale to get the current one, but the current one is always &quot;C&quot;, because to set the locale according to the environment variables we need to call setlocale with an empty string as locale. That's done by gtk_init(), which is called by all our binaries (web process, network process, etc.), but not by jsc (because jsc doesn't depend on GTK+). The reason why it has always worked for EFL is because they call ecore_init() in jsc that calls setlocale.</pre>
