UnicodeScripts.csGets the Script_Extensions of a code point: the scripts it is used with.
public static int GetScriptExtensions(int codePoint, Span<UnicodeScript> destination)Parameters
codePointint- The code point.
destinationSpan<UnicodeScript>- The buffer that receives the scripts, in increasing numeric value.
Returns
int The number of scripts written. It is 1, the script of UnicodeScripts.GetScript, for a code point that has no explicit Script_Extensions value.
Exceptions
ArgumentExceptiondestinationis too small.UnicodeScripts.MaxScriptExtensionCountelements are always enough.

HasScriptExtension(int, UnicodeScript)
UnicodeScripts.csDetermines whether a script is one of the Script_Extensions of a code point.
public static bool HasScriptExtension(int codePoint, UnicodeScript script)Parameters
codePointint- The code point.
scriptUnicodeScript- The script.
Returns
bool true when the code point is used with the script.
TryParseScript(ReadOnlySpan<char>, UnicodeScript)
UnicodeScripts.csGets the script that a name of the Script property designates, such as Latin or Latn.
public static bool TryParseScript(ReadOnlySpan<char> name, out UnicodeScript script)Parameters
