@LegionMammal978 so basically it might be useful in a non code golf challenge

RazetimeHusk, 20 bytes §:oa←tmo!¨nḂ+q²"ṗe¨→ Try it online! input as a list of digits. There's probably a better way to do the titlecasing part. Explanation §:oa←tmo!¨nḂ+q²"ṗe¨→ → increment input to accomodate 0-indexing mo map each digit to !¨nḂ+q²"ṗe¨ it's ...

Thinking of how to use Γ here

@Razetime I used it extensively in the left-hand answer to this challenge. (I haven't submitted it yet since the right-hand answer is still not done.)
Specifically, v and D (and technically things like E`R1) are the only possible numeric operations, so I use things like v5122132623DDD‼‼‼D‼‼‼D3556462 to construct a huge number several bits at a time
Interestingly enough, the inference for that kind of expression isn't even horribly slow

woah
that's an interesting challenge

For reference, here is the entire left-hand answer
Although now I'm pretty stuck with the right-hand answer
The characters allowed are ¦‼≡ "&'()*+,-./0789:;<=>?IJKLMNOPU[\]_ijklmnopu{|} and newline
With verbose mode, you can also use the commands ↑‰±₀₉Πμπ⁰⁹«
However, only \​ (swcase) and _ (tolowr) seem to be able to create characters from scratch, and I already have both cases
I was also thinking of using Haskell's character escapes, but r is unavailable here
@Razetime Do you have any ideas?

hmm
@LegionMammal978 so wait
this is for the right hand answer right
if there was a way for escaping unicode in a string it would be really convenient

@Razetime That's why I mentioned Haskell strings: Try it online! However, r is not allowed.

so there's no other way to use
like
"\u0495" for ҕ

@Zgarb I just remembered: you'd probably also want to modify the plainText++c:plainText2 in the maybeEscape expression to use the codepage
@Razetime No, you can look at the code, it currently only translates ¶¨¦ and interprets backslash escapes as literal characters.

@Zgarb Sorry for bothering you with so many notifications, but I think I found a somewhat simpler patch with the same effect (I end up turning findByte from getBytes into its own function):

Oh, also you can get the capital mu Μ in verbose mode with \\'\mu\​

I guess I'll just have to conclude that writing a right-hand program is impossible, due to the complete lack of relevant range or character manipulation commands
