##### Treat U+30A0 & U+30FB in Katakana Block as CJK
([#16796](https://redirect.github.com/prettier/prettier/pull/16796)
by [@tats-u](https://redirect.github.com/tats-u))
Prettier doesn't treat U+30A0 & U+30FB as Japanese. U+30FB is commonly
used in Japanese to represent the delimitation of first and last names
of non-Japanese people or “and”. The following “C言語・C++・Go・Rust” means
“C language & C++ & Go & Rust” in Japanese.
```md
C言
語
・
C++
・
Go
・
Rust
C言語・ C++ ・ Go ・ Rust
C言語・C++・Go・Rust
```
U+30A0 can be used as the replacement of the `-` in non-Japanese names
(e.g. “Saint-Saëns” (Charles Camille Saint-Saëns) can be represented as
“サン゠サーンス” in Japanese), but substituted by ASCII hyphen (U+002D) or
U+FF1D (full width hyphen) in many cases (e.g. “サン=サーンス” or “サン＝サーンス”).
##### Fix comments print on class methods with decorators
([#16891](https://redirect.github.com/prettier/prettier/pull/16891)
by [@fisker](https://redirect.github.com/fisker))
```jsx
// Input
class A {
@decorator
/**
* The method description
*
*/
async method(foo: Foo, bar: Bar) {
console.log(foo);
}
}
// Prettier 3.4.1
class A {
@decorator
async /**
* The method description
*
*/
method(foo: Foo, bar: Bar) {
console.log(foo);
}
}
// Prettier 3.4.2
class A {
@decorator
/**
* The method description
*
*/
async method(foo: Foo, bar: Bar) {
console.log(foo);
}
}
```
##### Fix non-idempotent formatting
([#16899](https://redirect.github.com/prettier/prettier/pull/16899)
by [@seiyab](https://redirect.github.com/seiyab))
This bug fix is not language-specific. You may see similar change in any
languages. This fixes regression in 3.4.0 so change caused by it should
yield same formatting as 3.3.3.
```jsx
// Input
foo
longlonglonglonglonglonglonglonglonglonglonglonglonglonglongl foo
, abc
;
// Prettier 3.4.1 (first)
foo
longlonglonglonglonglonglonglonglonglonglonglonglonglonglongl foo
, abc
;
// Prettier 3.4.1 (second)
foo
longlonglonglonglonglonglonglonglonglonglonglonglonglonglongl foo
, abc
;
// Prettier 3.4.2
foo
longlonglonglonglonglonglonglonglonglonglonglonglonglonglongl foo
, abc
;
```
