Insert a Unicode character by name

Alt+x insert-charCtrl+x 8 Enter】, then the name of the Unicode. For example, try to insert . Its name is “RIGHTWARDS ARROW”.

Insert a Unicode Char by Char ID in Hexadecimal

Alt+x insert-charCtrl+x 8 Enter】, then the hexadecimal of the Unicode.

For example, try to insert . Its hexadecimal value is “2192”.

Insert a Unicode Char by Char ID in Decimal

Insert letter with accent marks é

To see all characters you can type this way, press Ctrl+x 8 Ctrl+h. Example: ¿ ¡ ¢ £ ¥ ¤ § ¶ ® © ª «» × ÷ ¬ ° ± µ ÀÁÂÃÄÅÆ Ç ÈÉÊË ÌÍÎÏ ÐÑ ÒÓÔÕÖ ØÙÚÛÜÝÞß àáâãäåæç èéêë ìíîï ðñòóôõö øùúûüýþÿ.

If you need to type these chars often,

Alt+x set-input-method then type “latin-9-prefix”. That will allow you to type these chars without typing Ctrl+x 8 first.

(Emacs's “latin-9-prefix” corresponds to the char set ISO 8859-9)
