Executable-lookalike filename checks harder to fool

Filenames disguised to mimic existing executables are now much harder to sneak past.

What

The check for filenames that could collide with an existing .exe or .lnk file now defeats several disguises: characters from the U+F000-U+F0FF private-use block are mapped back to ASCII before comparing, trailing dots and spaces are stripped, and names are compared in both cases rather than lowercased once.

Details
  • The private-use unmapping step is new in this build.
Evidence

.exe.lnk

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
