Description

The Unicode character U+33D9, known as the SQUARE PPM, is a typographic symbol with specific roles and usage in digital text. It represents a square with an 'x' shaped projection at its center, which is often used to indicate a point of intersection or a point where two lines intersect in technical drawings, diagrams, and mathematical equations. This character is particularly useful in fields such as geometry, engineering, and physics where precise notation is required for accurate communication. Its square shape and the 'x' shaped projection at its center help provide visual clarity to readers by offering an intuitive representation of the concept being discussed. There may not be any specific cultural or linguistic context associated with this symbol, but it holds a significant value in technical contexts due to its ability to convey intersection points with precision.

How to type the symbol on Windows

Hold Alt and type 13273 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+33D9. 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+33D9 to binary: 00110011 11011001. 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:
    11100011 10001111 10011001
