This version is brought to you by the letter à and the number 0xC3.
👉 Tweaked the heuristic to decode, for example, "Ã " as the letter "à" more often.
This combines with the non-breaking-space fixer to decode "Ã " as "à" as well. However, in many cases, the text " Ã " was intended to be " à ", preserving the space -- the underlying mojibake had two spaces after it, but the Web coalesced them into one. We detect this case based on common French and Portuguese words, and preserve the space when it appears intended.
Thanks to @zehavoc for bringing to my attention how common this case is.
