ASCII printable characters
What are ASCII printable characters?
Codes 32 through 126 are the 95 printable ASCII characters - every character that produces a visible glyph. Code 32 is the space (technically printable but invisible), 48-57 are the digits 0-9, and 33-47, 58-64, 91-96, 123-126 are the punctuation and symbols.
These 95 characters are the safe set for cross-platform text: every terminal, editor, font, and protocol handles them identically. URL encoding only allows printable ASCII without escaping (except a few reserved characters). Programming languages universally support them in string literals. Need to type a character outside this range? Use ALT codes on Windows or HTML entities in web content.
