Unicode assigns stable code points to characters used across languages, writing systems, symbols, math notation, punctuation, and emoji.
Practical Notes
Unicode Practical Notes
Unicode gives characters stable identifiers, but display still depends on fonts, normalization, operating systems, and application support.
Code point vs glyph
A code point identifies a character. The visible shape depends on the font and rendering engine.
Combining marks
Some accents and symbols combine with nearby characters, which can affect searching, sorting, and string length.
Fallback fonts
If a character appears as a box or question mark, the active font probably lacks that glyph.

Unicode is the standard used to assign an unique number to each of the 144,697 characters expressed in world's text system. Unicode is comprised of multiple
languages, mathmetical symbols, historical scripts as well as emojies and non-visual control and formatting codes.
The first 128 characters of ASCII Codes are mapped to Unicode for backward compatibility, and hence ASCII is a subset of Unicode.
