The (hex.) column is the UTF-8 encoding of the character, that is, the sequence of bytes. The actual Unicode character number is the value in the first column, e.g., \u2190. So you should be able to type 2190 and get the character you want. Unicode is the character set and the character numbers (code points) are independent of how the characters are encoded. The encoding is how the characters are translated to bytes when written as a byte sequence. The Unicode standard defines a number of encodings, including UTF-8 and UTF-16. So there are not “UTF-8 characters”, only UTF-8 encodings of Unicode characters. The UTF-8 encoding was designed so that it is identical to ASCII for the first 127 or 255 characters (depending on which version of ASCII you’re looking at). But after character 255 it takes at least 3 bytes to encode a character.

Indeed I forgot about this feature in Oxygen: https://www.oxygenxml.com/doc/versions/19.1/ug-editor/topics/text-mode-actio... which basically allows you to type away the hex digits in Oxygen and then invoke the special "Convert Hexadecimal Sequence to Character" action.

The same probably for all other characters, type their decimal equivalent but it needs to be four typed figures. Oh, how quickly we forget certain things. :) oXygen has had the ability to enter UTF-8 characters in the first plane by their four character hexadecimal code point value since version 17.1. I can't recall what the default hotkey is for invoking it because I changed mine (back) to F8 as soon as I installed that version. I believe I've still got the plugin you guys provided me during my trial period for 17.0. Anyway, if Bernhard is happy with using hex instead of int, that's the solution instead of the Windows alt sequences (or the Mac alt/option sequences either, for that matter). .... bash-4.4$ unum.pl 0x1f926 Octal Decimal Hex HTML Character Unicode 0374446 129318 0x1F926 🤦 "🤦" FACE PALM bash-4.4$ Obviously some of us can see that character properly and some can't, but you all know which it is.
