Japanese imperial date regex:
Example: 令和5年2月 24 日
([令和|平成|昭和|大正|明治]{2})(\d+)年[\s]?(\d{1,2})[\s]?月[\s]?(\d{1,2})[\s]?日
@Jaha96 That doesn't catch all: the first year is commonly marked as 元年 instead of 1年. 令和元年 = year 2019, for example. This case was widely disregarded in many libraries, but in actual life, it was very common to see it written that way.
I'm working on Android and \d
matches 0
(U+FF10
), too.
This doesn't cover all kanjis. Simple example: 𧓈
To be fair those kanjis are extremely rare and are not used (they would not show up in dictionnaires or rikaichan like extensions) and 99.99% Japanese would not know about them:
https://en.wikipedia.org/wiki/CJK_Unified_Ideographs_Extension_B
Now you can match them with: [𠀀-𪛟]
and to match everything you would simply do: [𠀀-𪛟]|[一-龯]
@cb372, your list comes close to covering all the kana, but a few characters are still missing. You got 「ゞ」 but missed 「ゝ」 and 「ゟ」, and a few others. I believe this would cover all Hiragana and Katakana separately:
Hiragana = [ぁ-ゖ゛-ゟー]
Katakana = [゠-ヿ]
Combined Hiragana & Katakana would be:
Hiragana+Katakana = [ぁ-ゖ゛-ゟ゠-ヿ]
I used the above hiragana+katakana regex to validate the kana portions of the downloadable version of JMDICT and can confirm that apart from a few errors in the JMDICT data, the kana validation works.
