I would like to know if
Arial are 100% sure to be supported on website by any browsers/operation system; without that I need to use CSS3 for including font exclusively. I have been Googling that stuff, but I found only report of how big percentage of websites use them. But I don't know if there are any exceptions where
font-family: "Consolas", "Arial"; wouldn't be understand by system or browser.
I quite realise it sounds like dumpy-@@@ question but this would actually could change ways how I can code website. It sounds even more stupid than sense of asking of resolve.
