Which Font Has All Unicode Chars?

No single font has ALL Unicode chars. At best, they contain all chars in the Basic Multilingual Plane, meaning, the most commonly used ~65 thousand chars. (That is, 16 bits).

Font Substitution Tech

{Microsoft Windows, Mac OS X, Linux} all have Font substitution technology. When a char in the current font doesn't have a glyph, the system search for the glyph in other available fonts. So, this way, each font can be specially designed for a particular language or purpose, while you can still display many Unicode symbols in the same page.

As of 2021, today's font contain lots unicode, and also font substitution tech is robust. You can use Microsoft Windows Consolas or MacOS Menlo to display text with lots math symbols and it usually looks fine. But if you really use a lot math symbols, and want all characters to be aligned, JuliaMono, DejaVu Sans, Iosevka are the solution.
