Description

U+1DD4, the COMBINING LATIN SMALL LETTER AE, is a unique character in Unicode that plays an essential role in digital typography. This character is often employed to represent the combination of "a" and "e" in various languages. Its primary usage lies in textual contexts where a specific accent or style is required for these two letters to be combined. Although not commonly seen in everyday language, the COMBINING LATIN SMALL LETTER AE holds significance in certain cultural and linguistic contexts. In particular, it is used in the Old Icelandic alphabet, where it represents a single phoneme distinct from "a" and "e." This character helps maintain the integrity of words in Old Icelandic text by accurately representing the original pronunciation and meaning. In the realm of digital typography and Unicode, the COMBINING LATIN SMALL LETTER AE serves as a vital tool for maintaining consistency and precision in written communication across different languages and cultural contexts. By combining two individual letters into one, this character ensures that the intended message is conveyed accurately without ambiguity or confusion.

How to type the symbol on Windows

Hold Alt and type 7636 on the numpad. Or use Character Map.

  1. Step 1: Determine the UTF-8 encoding bit layout

    The character has the Unicode code point U+1DD4. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of 0x0800 to 0xffff.

    Therefore we know that the UTF-8 encoding will be done over 16 bits within the final 24 bits and that it will have the format: 1110xxxx 10xxxxxx 10xxxxxx
    Where the x are the payload bits.

    UTF-8 Encoding bit layout by codepoint range
    Codepoint RangeBytesBit patternPayload length
    U+0000 - U+007F10xxxxxxx7 bits
    U+0080 - U+07FF2110xxxxx 10xxxxxx11 bits
    U+0800 - U+FFFF31110xxxx 10xxxxxx 10xxxxxx16 bits
    U+10000 - U+10FFFF411110xxx 10xxxxxx 10xxxxxx 10xxxxxx21 bits
  2. Step 2: Obtain the payload bits:

    Convert the hexadecimal code point U+1DD4 to binary: 00011101 11010100. Those are the payload bits.

  3. Step 3: Fill in the bits to match the bit pattern:

    Obtain the final bytes by arranging the paylod bits to match the bit layout:
    11100001 10110111 10010100
