str_replace vs. preg_replace

Small, probably meaningless comparison between PHP[g] functions str_replace and preg_replace in processing of common string (un-recommended in the case of preg_replace: no regular expression search or replace: text only and result could be... well... not that one which you expected).

Enter the URL of web-page which is in Russian and choose correct encoding or use ready samples bellow; all page will be transliterated (cyrillic letters to latinic).
