Description

The Unicode character U+3358, known as the IDEOGRAPHIC TELEGRAPH SYMBOL FOR HOUR ZERO, holds significance in digital text for its role in representing a specific time unit in certain languages and contexts. This unique symbol finds its origins and application within the realm of Japanese telegraphy and is primarily used to denote the hour "0" (zero) in time-related messages. In this context, it serves as an essential tool for precise communication, particularly in historical documents and old telegrams where modern numeric characters may not have been widely adopted. Although its usage has waned with advancements in technology and standardization of character sets, the IDEOGRAPHIC TELEGRAPH SYMBOL FOR HOUR ZERO remains an interesting artifact of early digital typography and linguistic communication systems.

How to type the symbol on Windows

Hold Alt and type 13144 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+3358. 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+3358 to binary: 00110011 01011000. 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:
