Japanese font without Japanese character causes the clip at the bottom. A workaround that doesn't work.

JapaneseFontProblem.swift

import SwiftUI

struct SmapleView: View {

    let font = Font.custom("HiraginoSans-W3", size: 50)
    let borderColor = Color(.systemBlue)

    var body: some View {
        HStack(spacing: 10) {
            Text("Copy")
                .font(font)
                .frame(height: 60)
                .border(borderColor)

            Text("Copy")
                .font(font)
                .border(borderColor)
                .frame(height: 60)
                .border(borderColor)
        }
    }
}

struct SmapleView_Previews: PreviewProvider {
    static var previews: some View {
        SmapleView()
    }
}
