The goal of an HELLO WORLD is not to show it's printed, but the process of what everything is need to print HELLO WORLD. Every step, and every word and concept needs to be explained.

Therefore this article is not a proper HELLO WORLD exemple.

I guess Chinese characters work similarly, where eg, each character has a particular sound in Mandarin (with some characters having the same sound), but you spell words using certain characters based on the (sometimes historical) semantic association of components (radicals) within each character.

I'll admit I'm not an expert in either system, so sorry if either description seems like an oversimplification (I'm pretty sure there are exceptions in both cases).

This also leads to one of my favourite tables on Wikipedia [0], showing correspondences between various scripts, including Egyptian hieroglyphs and Arabic/Hebrew. Not all hieroglyphs are included, but you can see that each letter in Arabic/Hebrew ultimately derives from some hieroglyph which would have had a similar sound. The name of the Arabic letter ع sounds the same as the Arabic word for "eye" (ʿayn, عين) and the corresponding hieroglyph also looks like an eye.

So we have most of 𓇍𓇋𓏭𓂻𓍘𓇋𓇾𓂋𓇥𓂋𓈐𓆑 / jy.tj-tꜣ-r-ḏr-?? / "welcome land entire ??" except for the 𓈐𓆑 at the end where I have no idea whether it's phonetic ḥr=f or a determinative https://en.wiktionary.org/wiki/%F0%93%88%90 or something else.

As far as I can tell this is a transliterator, not a translator. It's just turning latin letters into hieroglyphs as you type them. I don't know how accurate the transliteration is.

It would be like coming up with a sequence of Chinese characters that sounds like an English sentence when pronounced by a Mandarin speaker. Nothing really to do with translation.

did the crossing of the rhine take place in 00406, 0406, or 406? what extra information do the two former styles convey?

also, what about the year 100000?

we are somehow doing just fine without leading zeroes for other quantities.

there is an argument to be made about e.g. iso8601 datetime formats that need to be lexicographically sortable; but i don't see any of the longnow fans using anything like those.

A study group or study partner would probably be enough extra motivation to get basic proficiency at the least. So if you're willing let me know if you find/wish to create something.
