HTML Entity Lookup

How to Use this HTML Entity Lookup Tool

This HTML Entity Lookup tool is a web-based utility designed to help users find information about HTML entities, including Unicode numbers, decimal and hexadecimal HTML codes, HTML names, and character descriptions. The tool also provides a visual representation of how the characters look.

Users can perform lookup by using one or more of the following patterns:

• Decimal numbers: for example, 34, 120, or 12*. The tool will search for a HTML entity with the matching code. An asterisk ('*') added at the end will make the search more inclusive and will bring the characters with partially matching codes.
• Hexadecimal numbers: for example, 3A, FA, x35, or x15*. The tool will look for a character with the corresponding hexadecimal code. An asterisk allows for partial match.
• Number range - decimal or hexadecimal: 34-120, 3A-FA, or x35-x120. The search will bring all entities with the code values within the provided range.
• Single character: for example, a, ë, or "$". The tool will display the details for the entered character.
• Text string: for example, fraction, nbsp, or "letter a". Users can enter a text string to search for HTML entities with matching text in their description or name. Text lookup is case insensitive.

Multiple comma-delimited (',') patterns can be provided.

Encoding HTML Entities

HTML entities are used to represent characters that may not be easily entered in HTML documents. They can be encoded within the document by HTML entity name, decimal, or hexadecimal representation.

• Decimal Encoding: To encode a character using its decimal representation, use the format:
  &#<decimal>;
  where <decimal> is the decimal value of the character.
• Hexadecimal Encoding: To encode a character using its hexadecimal representation, use the format:
  &#x<hex>;
  where <hex> is the hexadecimal value of the character.
• Encoding by HTML Entity Name: To encode a character using its HTML name, use the format:
  &<name>;
  where <name> is the name of the character. Note, HTML entity names are case-sensitive. For example, Atilde (Ã) and atilde (ã) are two different characters. Some characters have multiple names, for instance, "upwards arrow" (↑) - ShortUpArrow, UpArrow, uarr, and uparrow.

Often used character sets:
Arrows
ASCII Printable Characters
Box Drawing
