AirDC++ will now just replace invalid data when loading config files:
https://github.com/airdcpp/airgit/commit/6ab6e22770d1c6d61a5c25a6d58fb6cdedc67858

Since I generally expect this to affect only (a small number of)
favorite hub names and descriptions (and recent hubs in AirDC++), I find
the solution good enough for that. I can't think of any common cases
that would have caused other files to contain invalid data.

Title:
  Invalid UTF-8 data is not always being rejected

Status in AirDC++:
  New
Status in DC++:
  New

Bug description:
  There are various cases where invalid UTF-8 data is being consumed by
  the core:

  1. Text::convert will return the original string in case of errors (Linux only, respective Windows-specific functions will return an empty string in case of errors)
  2. When using "utf-8" encoding in NMDC hubs, the original string will always be returned by conversion functions without validation (generally Linux only since "utf-8" can't be selected from DC++'s GUI)
  3. UTF-8 validation is not performed for strings parsed from XML (specifically file/directory names in filelists)

  This will cause issues especially when the data is processed by
  external sources/libraries that expect to receive valid UTF-8 data
  (https://github.com/airdcpp-web/airdcpp-webclient/issues/204). I'm not
  sure about security implications.

  Another note: messages that fail UTF-8 validation in ADC hubs are
  ignored silently. At least Flexhub seems to be having problems with
  data validation which currently goes unnoticed.
