PureBASIC internal encoding of unicode, UCS-2 or UTF-16?

[Fred]

For the record, PB uses UCS2 string encoding internally when unicode mode is ON (it doesn't support multibyte UTF16 encoding).

For the record, PB uses UCS2 string encoding internally when unicode mode is ON (it doesn't support multibyte UTF16 encoding).

Does this mean that if Windows passes back a UTF-16 string where one character actually uses two UTF-16 "characters" then PureBasic will treat them as if they where two characters rather than a extended one?

(Similar to how a Ascii routine would treat a UTF-8 string with extended UTF-8 characters.)
