I tried the same query on both desktop and mobile, and I get asciitable.com as the top result on both, and neither of those top two sites you got show up on the first page. More on reddit.com

Both are ways for computers to encode text. ASCII is an old standard that use 1 byte per character. It is english centric and can't encode much more than the latin alphabet, which is problematic when dealing with non english content. UTF-8 is a newer standard that supports the full Unicode range (Unicode being a standard that aims to contain every possible character and symbol used by human languages, and more) while being retro-compatible with ASCII. This means that systems that were designed with ASCII in mind won't break when given UTF-8 and UTF-8 systems will process ASCII just fine, which is extremely important given the HUGE number of legacy ASCII only systems. There exists a bunch of other text encoding (like UTF-16 or UCS-2), but UTF-8 has proven much easier to work with and more efficient in the general case, so most text should now be encoded using UTF-8 whenever possible (The web is > 95% UTF-8).
