A useful webpage that I first saw in a tweet by Scott Chamberlain.
Displays Unicode characters on “buttons” that when selected displays the Unicode Hex code and HTML code for the selected character.
Quite useful when all you need is one entity value for a post.
If you need more information try Unicode Table – The Unicode Character Reference, which for “Latin Small Letter D” displays:
Unicode Character Information Unicode Hex U+0064 Character Name LATIN SMALL LETTER D General Category Lowercase Letter [Code: Ll] Canonical Combining Class 0 Bidirectional Category L Mirrored N Uppercase Version U+0044 Titlecase Version U+0044 Unicode Character Encodings Latin Small Letter D HTML Entity d (decimal entity), d (hex entity) Windows Key Code Alt 0100 or Alt +00641 Programming Source Code Encodings Python hex: u”\u0064″, Hex for C++ and Java: “\u0064” UTF-8 Hexadecimal Encoding 0x64
Or if you need all the information available on Unicode and to know it is the canonical information, see http://www.unicode.org/
