That's not a naming problem as much as it's a search engine problem. Search engines ignore anything that's not remotely alphabetic so for the longest time Google saw "C++ C#" as "C C". More and more characters are taken into account when searching these days, but it's still very error prone today.
If anything, C# was a mistake because it was developed after the first search engines entered the web. Then again, this was made by the same company that developed frameworks called "COM", "COM+" and ".NET". The names C and C++ were chosen way before this could have ever been perceived as a problem, because only lunatics and tinfoil hats could have predicted the internet in its current form all the way back in 1983.
In my experience, adding a revision (C99, C11, C17) to a search query often gets more relevant results specifically for C actual. For C++ the search term cpp always works for me. It's a bit of a pain to teach yourself to use, but after a while you start to get used to it.
Also choosing names with non-obvious pronunciation is also a peeve, sometimes it can become a marker between those who know how to pronounce it and those who don't. For example Godot.
