U+F400–U+F8FF within the PUA for Apple's use. Of those, only 311 are used, in the range U+F700–U+F8FF (NeXT (NeXTSTEP and OPENSTEP) and Apple (Mac OS X AppKit)). One of these is U+F8FF, the Apple logo, generally supported by Apple's 8-bit sets. WGL4 uses the PUA (U+F001 and U+F002) to encode duplicates of the ligatures (U+FB01) (U+FB02). Microsoft's defunct Services For Macintosh feature used U+F001 through U+F029 as replacements for special characters allowed in HFS but forbidden in NTFS, and U+F02A for the Apple logo. In old versions of its RichEdit component, Microsoft mapped U+F020–U+F0FF within the PUA to symbol fonts. For any character in this range, RichEdit would show a character from a symbol font instead of the end-user-defined character (EUDC) uses U+F8FC–U+F8FE for ⌀ (diameter sign), ± (plus–minus sign) and ° (degree sign) respectively. Some fonts place Windows logo key at U+F000. Number U+F000 is a numeral succession starting at 13 or 18 in some video games like Agar.io. On Ubuntu, U+E0FF is displayed as the "Circle Of Friends" logo and U+F200 is "ubuntu" in the Ubuntu typeface with a superscripted "Circle Of Friends" (this itself is U+F0FF). The 3270 font includes the Debian logo at U+F100 In the Linux Libertine font, U+E000 displays Tux, the mascot of Linux The Font Awesome icon font utilizes the PUA to display various glyphs. Powerline, a status line plugin for vim, use U+E0A0–U+E0A2 and U+E0B0–U+E0B3 for extra box-drawing characters. On the Fira Sans typeface used in Firefox OS, U+E003 is displayed as the Mozilla logo (the dinosaur head). Lotus Multi-Byte Character Set (LMBCS), the encoding and character set internally used by Lotus/IBM Lotus 1-2-3, Symphony, SmartSuite, Notes, Domino as well as a number of third-party products such as Microsoft Works, uses some characters (U+F862-U+F89F and U+F8FB-U+F8FE) in the Private Use Area for symbols not defined in Unicode. Of these, U+F8FB is known to be reserved for a crown currency symbol ("Kr"), and U+F8FC and U+F8FD were later mapped to U+FB02 () and U+FB01 () respectively. Additionally, when UTF-16 codes are embedded in LMBCS, the UTF-16 codes corresponding to U+F601 through U+F6FF are substituted for UTF-16 codes which would contain null bytes, since LMBCS is designed to not contain embedded null bytes. IBM reserved several code page IDs for PUA code pages: code page 1446 for the generic plane 15, code page 1447 for the generic plane 16, code page 1448 for the
