Micro Symbol not displaying in woocommerce module

Hey guys hope you can point in the right direction with this small issue.

I have a content slider with woocommerce products diplaying…
the product title includes a symbol for Micro Litre which is part of the Product title.. This displays correctly as the symbol everywhere, product listing, cart, etc. but on the product slider title it shows as “ML” if I change the case to Lower or none the “M” just dissapears.. Any suggestion where to look or the possible issue.
