Description

The Unicode character U+2031, known as the PER TEN THOUSAND SIGN, serves a crucial role in digital text by representing the Roman numeral symbol for ten thousand (X). This symbol is particularly prominent in mathematics and scientific fields where Roman numerals are used to denote large quantities. In addition, it finds usage in typography, historical documents, and cultural artifacts that use the Roman numeral system. Although modern culture has largely transitioned to the Arabic numeral system for ease of understanding, the PER TEN THOUSAND SIGN remains a significant element in maintaining the integrity and preservation of ancient numerical systems.

How to type the symbol on Windows

Hold Alt and type 8241 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+2031. 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+2031 to binary: 00100000 00110001. 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:
    11100010 10000000 10110001
