Description

U+0227, known as the "Latin Small Letter A with Dot Above," is a Unicode character that plays a significant role in digital text. It represents a lowercase 'a' with a dot above it, which makes it easily distinguishable from other similar characters. This typographic symbol is primarily used to represent specific phonological features in various languages, such as the /ə/ sound in the International Phonetic Alphabet (IPA). Its cultural, linguistic, and technical context is centered around clarity and precise communication, particularly in transcription and translation. As a result, U+0227 is widely used in academic texts, dictionaries, and language learning resources. By incorporating this character into digital text, authors and editors can ensure accuracy and avoid confusion in their written work.

How to type the ȧ symbol on Windows

Hold Alt and type 0551 on the numpad. Or use Character Map.

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

    The character ȧ has the Unicode code point U+0227. In UTF-8, it is encoded using 2 bytes because its codepoint is in the range of 0x0080 to 0x07ff.

    Therefore we know that the UTF-8 encoding will be done over 11 bits within the final 16 bits and that it will have the format: 110xxxxx 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+0227 to binary: 00000010 00100111. 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:
