user1398: To be more precise, there are quite a number of anime/manga that follows Cypher Language Trope.
Examples of Cypher Language:

Maoyuu Maou Yuusha on TVTropes
Substitution chart for some anime on rickadams.org

Can we ask for exhaustive list of transcription of all the ciphertext in the anime/manga?

user24: I think it's fine to ask how to decipher encoded text in some anime, as in What do the Runes say in Madoka?. I also think it would be fine to answer such a question with an exhaustive list of all of the encoded text, though that isn't what was done in this case.
Whether it's appropriate to ask for a full list of deciphered text depends on how much is present in the source and how easy it is to find. In a case like Madoka, this was an effort that required people to go frame-by-frame through the anime to make sure nothing was missed, translating the runes to German, and then getting someone to translate the German to English. The whole process took a lot of people and many hours.
If you're asking someone to do all of that work from scratch, the question isn't reasonably scoped in my opinion*. Questions here should be things that people are able to answer without doing a large amount of work on their own. Practically, what's likely to happen in these cases is that the question just goes unanswered for a long time. On the other hand, if there are only a few instances of encoded text, which are fairly easy to find, and the code is known, I think it's fine.
What exactly constitutes the boundary is up for debate. From What is the status of list questions on this site?, the criterion for a list question to be reasonably scoped is:

If you can imagine an entire wiki-page listing your answer, the question is not reasonably scoped.

which I think is reasonable to apply in this case as well.

*I'd make an exception in the case that you are answering your own question. In that case, in my opinion the "reasonably scoped" criterion becomes irrelevant.
