Characters and text rules in one place
The alphabet catalogue leads to a dedicated page for each language, with letters in standard order and paired uppercase and lowercase forms.
The text-art collection keeps multiline character drawings ready to paste, while kaomoji groups text faces by emotion and action. The Alt code table explains numeric-keypad input, and the emoji catalogue finds pictographs by meaning, shortcode, or Unicode sequence.
Text art, kaomoji, Alt codes, emoji, examples, characters, byte sequences, HTML markup, Markdown, and regular expressions can be copied directly. The reference pages remain readable without client-side scripts.
