U+23CF Eject Symbol

U+23CF was added in Unicode version 4.0 in 2003. It belongs to the block U+2300 to U+23FF Miscellaneous Technical in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Other Symbol and is commonly used, that is, in no specific script.

The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. The word that U+23CF forms with similar adjacent characters prevents a line break inside it.

The CLDR project calls this character “eject button” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: eject.

This character is designated as an emoji. It will be rendered as monochrome character on conforming platforms. To enable colorful emoji display, you can combine it with Glyph for U+FE0F Variation Selector-16: ⏏️ See the Emojipedia for more details on this character’s emoji properties.

The Wikipedia has the following information about this codepoint:

In computing, a removable media is a data storage media that is designed to be readily inserted and removed from a system. Most early removable media, such as floppy disks and optical discs, require a dedicated read/write device (i.e. a drive) to be installed in the computer, while others, such as USB flash drives, are plug-and-play with all the hardware required to read them built into the device, so only need a driver software to be installed in order to communicate with the device. Some removable media readers/drives are integrated into the computer case, while others are standalone devices that need to be additionally installed or connected.

Examples of removable media that require a dedicated reader drive include:

  • Optical discs, e.g. Blu-rays (both standard and UHD versions), DVDs, CDs
  • Flash memory-based memory cards, e.g. CompactFlash, Secure Digital, Memory Stick
  • Magnetic storage media
    • Floppy and Zip disks (now obsolete)
    • Disk packs (now obsolete)
    • Magnetic tapes (now obsolete)
  • Paper data storage, e.g. punched cards, punched tapes (now obsolete)

Examples of removable media that are standalone plug-and-play devices that carry their own reader hardwares include:

  • USB flash drives
  • Portable storage devices
    • Dedicated external solid state drives (SSD)
    • Enclosured mass storage drives, i.e. modified hard disk drives (HDD)/internal SSDs
  • Peripheral devices that have integrated data storage capability
    • Digital cameras
    • Mobile devices such as smartphones, tablets and handheld game consoles
    • Portable media players
  • Other external or dockable peripherals that have expandable removable media capabilities, usually via a USB port or memory card reader
    • USB hubs
    • Wired or wireless printers
    • Network routers, access points and switches

Using removable media can pose some computer security risks, including viruses, data theft and the introduction of malware.
