Description

The Unicode character U+25C1 represents the "White Left-Pointing Triangle" in digital text. This symbol is commonly used to indicate directions, such as when guiding the user through a series of steps or instructions. It is frequently seen in software applications, documentation, and online help files as a visual guide for users to follow sequential processes. The triangle's orientation (left-pointing) signifies that the action should be taken before proceeding further. The White Left-Pointing Triangle is an important tool in user experience design, as it helps users navigate through complex tasks by providing clear and concise directional cues.

How to type the symbol on Windows

Hold Alt and type 9665 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+25C1. 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+25C1 to binary: 00100101 11000001. 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 10010111 10000001
