Name an Armor Stand using the Standard Galactic Alphabet

Solution 1:

Unfortunately, there is no way to name any entity using the Standard Galactic Alphabet. The closest you will get is to use the LingoJam translator characters. You can only name an entity with Unicode characters so you can not name an armor stand with Standard Galactic Alphabet characters. You could create a texture pack and change some of the Unicode characters to look like Standard Galactic Alphabet Characters. Here is some more information on that. https://minecraft.gamepedia.com/Resource_pack#Fonts

Solution 2:

What the enchanting table uses is just a different font. The text in it is just a random arrangement of words listed here (archive).

So the way to write with it would be a resource pack that replaces the font or to use Unicode characters that look similar, which you have denied for some reason.
