発音区別符号が使用されている場合の \caption の奇妙な動作

発音区別符号が使用されている場合の \caption の奇妙な動作

画像のキャプションに分音記号文字が含まれている場合、\caption で気になる問題が発生します。分音記号は問題なく表示されますが、キャプション自体は中央揃えではなく左揃えになります。私の環境でキャプションにこのような動作が発生する理由について何かご存知ですか?

これにより、次のようなあまり良くない両端揃えのキャプションが生成されます。

ここに画像の説明を入力してください

答え1

通常、複数行のキャプションは両端揃えになります。中央揃えにしたい場合は、 を使用する必要があります\captionsetup{justification=centering}

注: 変更の一部は完全に不必要なものです。
