I think, the encoding detection issues are vastly resolved, but I'll drop here some samples which are still failing.

Idea of algorithm for new heuristic

Let S be an input string of length N
Score ← 0
Counter ← 0
Script ← None
For each codepoint C of S:
    PreviousScript ← Script
    Script ← uscript_getScript(C)
    If Script ≠ PreviousScript:
        Counter ← 0
    Counter ← Counter + 1
    Score ← Score + Counter
Score ← Score / N
