Description

U+03B1 is the Unicode character code for the Greek lowercase letter 'alpha'. As an important letter in the Greek alphabet, it plays a crucial role in both ancient and modern textual applications. In digital text, the alpha character is often utilized to represent the beginning of a sequence or list, similar to how the Latin 'A' is used in English. This versatile symbol can also be employed as a variable in mathematical equations and computer programming due to its unique value. Beyond typography, the Greek alphabet has played a significant role in various historical and linguistic contexts, such as the foundational basis for the Roman alphabet that we use today.

How to type the α symbol on Windows

Hold Alt and type 0945 on the numpad. Or use Character Map.

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

    The character α has the Unicode code point U+03B1. 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.

    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+03B1 to binary: 00000011 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:
