setupEncoding
in class WinFunctionCache
public boolean isUnicode()
Detects the platform if this wasn't done before, or property wasn't
explicitly modified directly via setUnicode()
. If the
property wasn't set explicitly, assumes that Unicode should be used if
the underlying OS is NT-based.
NOTE: Since the Unicode support detection is based on the platform version
detection, which itself requires Kernel32
instance, the
detection cannot be performed in the constructor to prevent recursion,
and should be delayed until actually queried.
