[Plugin: Transliterado] Call to undefined function

There is a message right after installing plugin on wordpress (last version):

Fatal error: Call to undefined function mb_check_encoding() in ***/docs/wp-content/plugins/transliterado/transliterado.php on line 58

P.S.: after some googling it seems that I need to enable mbstring module on server to fix it. I’ll try it soon…
