Description

The Unicode character U+1AB1, COMBINING DIAERESIS-RING, is a specialized typographic symbol used primarily in digital text to represent the diacritical mark known as diaeresis or umlaut (¨). It is often employed in various languages to modify the pronunciation of certain vowels, such as in German, Swiss German, and Dutch. The diaeresis indicates a change in vowel sound, where an "i" or "u" with this mark is pronounced as a separate vowel rather than being part of a diphthong. In a technical context, the COMBINING DIAERESIS-RING can be used alongside other combining characters to create composite marks that may not have direct Unicode representations. As an essential element in accurate and culturally appropriate transcription, the U+1AB1 character plays a vital role in digital typography for languages that utilize diaeresis or umlauts.

How to type the symbol on Windows

Hold Alt and type 6833 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+1AB1. 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+1AB1 to binary: 00011010 10110001. 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 10101010 10110001
