[RESOLVED] what is exactly ChrW function?

hello everyone

so i have this question about the ChrW function let's say for example we do this

char = ChrW(1584)

then if we write the char variable in a file and we hex edit it we can see that the hex representation of that variable is \xd0 even if the Character unicode of 1584 is '\u0630' which is '\xd8\xb0' so i just want to know how chrw function work i mean how come that it return only one byte even if it's unicode

Thank You so much
