+Don't set locale explicitly. musl supports UTF-8 by default.
+
+With this change pdfgrep fails with:
+
+        terminate called after throwing an instance of 'std::runtime_error'
+          what():  locale::facet::_S_create_c_locale name not valid
+        Aborted
+
+Unless LANG is set explicitly.
+
+Alternative solutions:
+
+        * Use the "C" lang instead of the "" lang?
+        * Catch the error and ignore it?
