The GB18030 encoding standard is a mandatory Chinese character encoding 
standard required by regulations. Software sold and used in China must 
support GB18030, with its latest version being the 2023 edition. The 
primary advantage of GB18030 is that most Chinese characters require 
only 2 bytes for storage, whereas UTF-8 necessitates 3 bytes for the 
same characters. This makes GB18030 significantly more storage-efficient 
compared to UTF-8 in terms of space utilization.
