Description

The Unicode character U+30E9 represents the Katakana letter "ら" (Ra) in the Japanese writing system. In digital texts, this character is primarily used for representing the voiced alveolar trill, a speech sound that occurs at the alveolar ridge in the oral cavity. This character holds cultural and linguistic significance, as it is one of the 46 basic Katakana characters used in the Japanese language, and forms part of the larger Katakana script derived from the older Hiragana writing system. The Katakana script is predominantly employed for borrowed words from foreign languages, onomatopoeic expressions, and proper names in written Japanese. As an essential component of the Japanese writing system, U+30E9 contributes to the accuracy and comprehensibility of digital texts in the language.

How to type the symbol on Windows

Hold Alt and type 12521 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+30E9. 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+30E9 to binary: 00110000 11101001. 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 10000011 10101001
