function UnicodeIsSurrogatePair( |
const AHighSurrogate: UnicodeChar; |
const ALowSurrogate: UnicodeChar |
):Boolean; |
AHighSurrogate |
|
High character in the surrogate pair. |
ALowSurrogate |
|
Low character in the surrogate pair. |
True if AHighSurrogate,ALowSurrogate are a valid surrogate pair.
UnicodeIsSurrogatePair checks whether AHighSurrogate,ALowSurrogate constitute a valid surrogate pair, and returns True if this is the case. It does this by checking whether the values are within the bounds for high and low surrogate pairs.
