ASCII tab lists all 128 control + printable characters with decimal, hex and name. Extended tab lists 128-255 (ISO-8859-1 / Latin-1). Use the search box in either tab to filter. The Converter does both directions: paste any character to get its Unicode codepoint (U+XXXX), decimal, UTF-8 byte sequence and UTF-16 code units; or enter a codepoint in U+XXXX / 0xXXXX / decimal form to render the character. Surrogate-pair characters (emoji, CJK Ext) are handled via code-point iteration.
