node::base64_encode() uses ::base64_encode() when the mode is Base64Mode::NORMAL, so base64_select_table is only ever called for Base64Mode::URL and thus only ever returns base64_table_url, but never base64_table. Also move base64_table_url into base64-inl.h. PR-URL: https://github.com/nodejs/node/pull/44425 Reviewed-By: James M Snell <jasnell@gmail.com> Reviewed-By: Minwoo Jung <nodecorelab@gmail.com>
