Twitter Text Obj VS spring-boot-starter

I recall that Twitter allowed 140 Chinese characters in tweets originally, but when they switched to 280 ascii characters, CJK languages were not included. The current documentation does say that some languages and emojis use 2 characters per symbol of the 280 limit, limiting those languages to 140. https://developer.twitter.com/en/docs/counting-characters

I assume you we’re going for half of the (new) character limit? That wouldn’t be bad as a rough guess, except Twitter uses UTF-8 encoding and what counts as a character is a bit complicated. Certain objects like usernames in a reply or image URLs hosted on Twitter are not counted, either. The maximum size of a modern tweet could therefore be upwards of 280 x 4 = 1,120 bytes.

Given the examples in this article it seems like it could potentially be used for this!

It turns out, working this out is non-trivial, as Twitter has a few rules around how it count's characters. These are basically:

Japanese, Korean and Chinese were excluded from that increased cap, because they already had a significant advantage in being able to put more information into a single character. (More specifically, it's implemented such that ideograms count as 2 characters now, and emoji do, too.)

The 280 character limit in a tweet isn't equal to the number of glyphs in a tweet.

You may find that after getting a good amount of foundational knowledge or experience, books are only good for author perspective. In the wild, maybe you'll benefit more from a boilerplate / starter repo like this or this. Those are called starters / boilerplate repos. That's a good way to get started if the getting started docs of your chosen tech is intimidating or confusing. Here's the one for spring boot.
