Description

The Greek Capital Letter Tau (U+03A4) is a crucial character within the Unicode standard, representing a specific letter from the Greek alphabet. In digital text, it often serves as a typographical element in various applications such as mathematics, computer science, and linguistics. Its cultural significance lies in its historical usage within the ancient Greek language, where it was one of the 24 original letters. The Tau symbol holds particular importance in mathematics, specifically in topology and geometry, where it is used to denote the concept of torus, a surface of revolution generated by revolving a circle around an axis. In computer science, the character is frequently employed in domain names registered with internationalized top-level domains (IDNs) that use Unicode characters. Thus, the Greek Capital Letter Tau showcases both cultural and technical applications across various disciplines.

How to type the Τ symbol on Windows

Hold Alt and type 0932 on the numpad. Or use Character Map.

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

    The character Τ has the Unicode code point U+03A4. 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+03A4 to binary: 00000011 10100100. 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:
