What it does

Step	Example	Default
Full-width → half-width ASCII	`ＡＢＣ１２３` → `ABC123`	on
Half-width katakana → full-width	`ｶﾞｷﾞ` → `ガギ`	on
Ideographic space → space	`東京　都` → `東京都`	on
Unify dashes (keeps the long vowel ー)	`03−1234–5678` → `03-1234-5678`	on
Collapse spaces, trim lines		on
Postal code format	`〒1000001` → `〒100-0001`	on
Japanese era date → ISO	`令和6年4月1日` → `2024-04-01`, `R5.12.31` → `2023-12-31`, `平成元年` → `1989`	off
Kanji numerals → Arabic (experimental)	`三万五千円` → `35000円`	off

Era dates (令和 / 平成 / 昭和 / 大正 / 明治, also R6.4.1, H31.4.30 style) are always detected and listed in warekiDates, even when the rewrite option is off. Impossible dates (令和2年2月30日) and dates outside the era (平成31年5月1日) come back with a warning and are never rewritten.

Symbols such as ① or ㈱ are intentionally left as they are (unlike plain NFKC).

Pricing

Pay per event, platform usage included:

Event	Price
Actor start	$0.01 per run
`text-normalized` – one input text normalized	$0.50 per 1,000 texts

Example: normalizing 10,000 texts costs $0.01 + $5.00 = $5.01.

Limits

Kanji numeral conversion is heuristic and off by default. Words such as 四国 can be changed. Check the output.
Era years are converted using the first year of each era (令和1 = 2019, 平成1 = 1989, 昭和1 = 1926, 大正1 = 1912, 明治1 = 1868).
