There are many ideographic characters and uncommon complex glyph characters in the Simplified Chinese character library. These characters are classified according to frequency of use, and many of them are not necessarily supported by the operating system. For example, the very famous Biangbiang noodles cannot be displayed on most computers. This character is said to be one of the most complex Chinese characters, but it already has its own Unicode character code: U+30EDD
In the Windows 11 DevBuild 26120.1930 version launched last week, Microsoft added a simplified Chinese font extension support set (Simsun-ExtG). This new support set contains 9753 ideograms and supports Unicode extensions G, H and I, including the word Biang.
In other words, after this update, users can correctly display special Chinese characters such as Biang on Windows 11. Of course, in addition to the support provided by the operating system, it also requires software support. Most current software may not be able to display such Chinese characters properly, so it will still be displayed as an alternative "口".
This updated character set includes the following Unicode ranges:
Unicode range G30000-3134A (4,939 characters)
Unicode range H31350-323AF (4,192 characters)
Unicode range I2EBF0-2EE5D (622 characters)
