Open up your minecraft.jar in something like 7-zip or winrar, and go into the "font" folder. There are a ton of files in this folder, but there are only two you need to use: "default.png" and "alternate.png". Rename "alternate.png" to "alternate1.png" (You can actually rename it to whatever you want, but alternate1.png is really easy to find again.) Then duplicate "default.png" and rename the copy to "alternate.png". And that's it. The "code" is just a font. Minecraft will now use the default font for enchantments.
Nope, it isn't usefull unless you're wondering what the magic words are. Even though they're randomly selected from that mentioned list. It's more cosmetic than anything, and also, from what i understand you can simply change the font if you know what you're doing so that it all reads in normal font.
Clever? Yes. Although anyone who has read the wiki or played the "Commander Keen" games will recognize the Galactic Standard Alphabet.
It's purely cosmetic and enchantments are based on a basic RNG program (Random Number Generator) to decide the default values of an enchantment based on a series of randomly generated dice rolls to simulate chance based on percentages. At least that's what i'm assuming.
A common example of RNG's is any game or even java based chat applet that has dice rolls as an emote or function in game. Particularly D&D based games use RNGS almost to the point of one getting sick of them (Neverwinter Nights, Baldurs Gate, etc.)
Although D&D games usually aren't Java based. At least these ones mentioned.
I was under the impression from the Wiki that this was common knowledge.
The creator never claimed this would be able to decipher which enchantment you were going to get...it just said that it would help you translate the name of the enchantment option you were selecting into English. Please read before you complain, people.
uh i think he worded it badly:
This program can help you in translating spells. it should have said translating the words
