HTC, add emoji presentation to some other existing Unicode characters or coin their own ZWJ sequences. Microsoft displayed all

While only is officially an emoji, Microsoft and Samsung add the other three directions as well (, , ). Microsoft no longer supports these emojis now. Both vendors pair the standard checked ballot box emoji with its crossed variant , but only Samsung also has the empty ballot box . Samsung almost completely covers the rest of the
Miscellaneous Symbols block (U+2600‥FF) as emoji, which includes chess pieces, game die faces, some traffic sign as well as genealogical and astronomical symbols for instance. HTC supports most additional pictographs from the
Miscellaneous Symbols and Pictographs (U+1F300‥5FF) and
Transport and Map Symbols (U+1F680‥FF) blocks. Some of them are also shown as emoji on Samsung devices. The open source projects Emojidex and Emojitwo are trying to cover all of these extensions established by major vendors. ==See also==
