Writing special characters in the new interface

I don't know, what ULS is, but while I am typing these words, I have a list of clickable special characters and character sequences below the editing field:

Edittools ("<!-- Text here will be shown below edit and upload forms. -->")

Special characters: Á á É é Í í Ó ó Ú ú Ý ý – À à È è Ì ì Ò ò Ù ù –  â Ê ê Î î Ô ô Û û – Ä ä Ë ë Ï ï Ö ö Ü ü Ÿ ÿ – Æ æ Ø ø Œ œ ẞ ß – Å å Ů ů – à ã Ẽ ẽ ɛ̃ Ĩ ĩ Ñ ñ Õ õ ɔ̃ Ũ ũ – Ð ð Þ þ – Ç ç Ģ ģ Ķ ķ Ļ ļ Ņ ņ Ŗ ŗ Ş ş Ţ ţ – Ć ć Ĺ ĺ Ń ń Ŕ ŕ Ś ś Ý ý Ź ź – Č č Ď ď Ľ ľ Ň ň Ř ř Š š Ť ť Ž ž – Ǎ ǎ Ě ě Ǐ ǐ Ǒ ǒ Ǔ ǔ – Ā ā Ē ē Ī ī Ō ō Ū ū – ǖ ǘ ǚ ǜ – Ĉ ĉ Ĝ ĝ Ĥ ĥ Ĵ ĵ Ŝ ŝ Ŵ ŵ Ŷ ŷ – Ă ă Ğ ğ Ŭ ŭ – Ċ ċ Ė ė Ġ ġ Għ għ İ ı Ż ż – Ą ą Ę ę Į į Ų ų – Ő ő Ű ű – Đ đ Ħ ħ Ł ł Ŀ ŀ – Ɖ ɖ Ɛ ɛ Ƒ ƒ Ɣ ɣ Ŋ ŋ Ɔ ɔ Ʋ ʋ - Ə ə – – — ־ ’ – ~ | ° ¹ ² ³ ⅛ ¼ ⅓ ⅜ ½ ⅝ ¾ ⅔ ⅞ € $ ¥ £ † × ← → ↔ ↑ ± ≠ © ® ™ ‰ «» ‹› „“ „” ‚‘ ¡ ¿ … – &nbsp; &nbsp; [[Category:]] #REDIRECT[[]] {{msg-mw||notext=1}} !!FUZZY!! ~~~~ <nowiki></nowiki> ڈ ڑ ٹ ټ څ ځ ډ ړ ږ ښ ڼ ؤ ي ې ۍ ئ {{{}}} {{}} {{subst:}} <noinclude></noinclude> <!--&nbsp;&nbsp;--> <br&nbsp;/>

We had that once with message editing, too. If I'm not mistaken, we got three new versions of editing meanwhile, with this most useful feature disabled, or missing. I would like to have it back, or something similar, and I am truly sad that I do not have the means and the capacity at the moment to add it to the new editor, if possible.
