	Note:

Symbols for Legacy Computing Supplement is a Unicode block containing additional graphic characters that were used for various home computers from the 1970s and 1980s. It includes characters from Amstrad CPC, Apple 8-bit, Kaypro CP/M, Ohio Scientific, Robotron KC, Sharp MZ computers, HP terminals, and TRS-80. It includes a set of semigraphics in the form of 230 "octant" characters, large images split into four "characters", and the "large type" characters used for building large text characters.^[3]

Block

This table contains uncommon Unicode characters. Without proper rendering support, you may see question marks, boxes, or other symbols instead of the intended characters.
