Here is the website which uses the font I am trying to identify:

I would be super grateful for any help!
Many thanks,

The website is a mess. 
Looks like an ordinary sans serif font but they happen to have randomly replaced some basic latin characters with characters from the Letterlike Symbols unicode block. For instance the blackletter R which keeps appearing, the script l and the ‘per’ symbol instead of a lowercase p, but they haven’t replaced all instances of those characters.
The standard letters design could have started from something like Lightline Gothic by Monotype, Berthold or Mannesmann Scangraphic for instance.
with outlining, squashing and a better /M.
I think the capital M which sometimes appears is the script M from the Letterlike Symbols block.
