Artio JoomSEF: 3.5.5

Virtuemart: 1.1.4


I am trying to make my meta descriptions appearing in Google snippets more catchy and appealing. Having seen that some sites are using Unicode-symbols instead of text, I decided to follow suit. First of all, I want to replace "phone" with ☎ (☎). Unfortunately, whenever I put ☎ in Meta Description field (JoomSEF - SEF Url [ Change ]) and then click "Save" the telephone symbol is replaced with question mark (?).

Any helpful advice is welcome.
