Space is 32Space (0x20) is the first printable character. It counts as a character, not nothing.
ASCII vs UnicodeASCII is a 7-bit subset of Unicode. Every ASCII code maps 1:1 to the same Unicode code point, so ASCII text is valid UTF-8.
DEL at 127127 (0x7F) is the delete character, not a printable glyph. Old terminals used it to rub out the previous char.
