  • Have a look at https://stackoverflow.com/questions/809620/correct-terminology-between-utf8-and-utf-8. Read comments as well. This (https://www.effectiveperlprogramming.com/2011/08/know-the-difference-between-utf8-and-utf-8/) is about Perl, but might be an interesting reading. – Littlefoot Nov 22 '22 at 07:47
  • Should I use UTF-8 or UTF8 for word: "Xin chào các bạn trên toàn thế giới." ? – Vy Do Nov 22 '22 at 07:49

    UTF-8 *should* be the one. – Littlefoot Nov 22 '22 at 07:56

    Oracle uses term `UTF8` for Character set [CESU-8](https://en.wikipedia.org/wiki/CESU-8). The Character set name for "proper" UTF-8 is `AL32UTF8`. However, I don't know if this also applies to Oracle SQL-Developer or only to Oracle Database. – Wernfried Domscheit Nov 22 '22 at 08:21
