Can't get Chinese Font to work

[th3impal3r]

I am trying to localize a PDF in Chinese, Korean, and Japanese.

I was able to get the Korean font to work, but for Chinese and Japanese I get
Error: Not a CFF Font

Here is my font def:

const fonts = {
    // English
    HelveticaNeue: {
        normal:  [`${fontsDir}/HelveticaNeue.ttc`, 'HelveticaNeueLTStd-Md'],
        bold:  [`${fontsDir}/HelveticaNeue.ttc`, 'HelveticaNeueLTStd-Bold'],
    },
    HelveticaNueuRoman: {
        normal:  [`${fontsDir}/HelveticaNeue.ttc`, 'HelveticaNeueLTStd-Roman'],
        bold:  [`${fontsDir}/HelveticaNeue.ttc`, 'HelveticaNeueLTStd-Bold'],
    },
    // Korean
    AppleSDGothicNeo: {
        normal: [`${fontsDir}/AppleSDGothicNeo.ttc`, 'AppleSDGothicNeo-Regular'],
        bold: [`${fontsDir}/AppleSDGothicNeo.ttc`, 'AppleSDGothicNeo-Bold'],
    },
    // Chinese
    PingFangSC: {
        normal: [`${fontsDir}/PingFang.ttc`, 'PingFangSC-Regular'],
        bold: [`${fontsDir}/PingFang.ttc`, 'PingFangSC-Semibold'],
    },
    // Japanese
    HiraginoSansGB: {
        normal: [`${fontsDir}/HiraginoSansGB.ttc`, 'HiraginoSansGB W3'],
        bold: [`${fontsDir}/HiraginoSansGB.ttc`, 'HiraginoSansGB W6'],
    },
};
