Zwei At-Zeichen: @ und ＠
I never realized there were actually two distinct AT-Signs: the regular "@" and the fullwidth "＠".
- U+0040 @ COMMERCIAL AT
- U+FF20 ＠ FULLWIDTH COMMERCIAL AT Ironically, Udemy is now blocking the use of the "@" sign in descriptions, deeming it to resemble an email address. A rather debatable choice in the context of Java annotations.
