I have just published a picker for Egyptian Hieroglyphs.

This Unicode character picker allows you to produce or analyse runs of Egyptian Hieroglyph text using the Latin script.

Characters are grouped into standard categories. Click on one of the orange characters, chosen as a nominal representative of the class, to show below all the characters in that category. Click on one of those to add it to the output box. As you mouse over the orange characters, you’ll see the name of the category appear just below the output box.

Just above the orange characters you can find buttons to insert RLO and PDF controls. RLO will make the characters that follow it to progress from right to left. Alternatively, you can select more controls > Output direction to set the direction of the output box to RTL/LTR override. The latter approach will align the text to the right of the box. I haven’t yet found a Unicode font that also flips the glyphs horizontally as a result. I’m not entirely sure about the best way to apply directionality to Egyptian hieroglyphs, so I’m happy to hear suggestions.

Alongside the direction controls are some characters used for markup in the Manuel de Codage, which allows you to prepare text for an engine that knows how to lay it out two-dimensionally. (The picker doesn’t do that.)

The Latin Characters panel, opened from the grey bar to the left, provides characters needed for transcription.

In case you’re interested, here is the text you can see in the picture. (You’ll need a font to see this, of course. Try the free Noto Sans font, if you don’t have one – or copy-paste these lines into the picker, where you have a webfont.)
𓀀𓅃𓆣𓁿
<-i-mn:n-R4:t*p->
𓍹𓇋-𓏠:𓈖-𓊵:𓏏*𓊪𓍺

The last two lines spell the name of Amenhotep using Manuel de Codage markup, according to the Unicode Standard (p 432).
