Conversion Data

Default conversion pairs are based on DrTurnon/kyujipy's kyujitai_simplified list (MIT licensed). Structure matches the original CSON format:

# Example from source data
[
    ["亜", "亞"],
    ["悪", "惡"],
    ["圧", "壓"],
    ["囲", "圍"]
]

Advanced Usage

Line-Specific Conversion:

Prefix lines with your symbol to convert only those lines:

> 聖アレキセイ寺院の殺人事件に法水が解決を公表しなかつたので、そろ〱迷宮入りの噂が立ちはじめた十日目のこと、その日から搜査關係の主腦部は、ラザレフ殺害者の追求を放棄しなければならなくなつた。 (converted)
この書き出しから始まる『黒死館殺人事件』は、小栗虫太郎による長編探偵小説であり、日本探偵小説の「三大奇書」の一つとも称される。 (unconverted)

Exclusion Protection:

Preserve specific combinations during conversion:

// kyujify.exclusions = ["欠缺"]
欠缺 -> remains 欠缺 (instead of 欠欠 or 缺缺)
