A class that randomly generates simplified Chinese characters

Static string [] fonts (INT strlength)
// Return: string (), a one-dimensional random simplified Chinese character string array of strlength characters ()

Static object [] createregioncode (INT strlength)
// This function randomly creates a hexadecimal byte array containing two elements within the Chinese character encoding range. Each byte array represents a Chinese character and stores four byte arrays in the object array.
