Error: Only 8, 16, 24, or 32 bits supported: 608 in certificationRequestFromPem

Hello!

When I create a certificate request, convert it to PEM format, and then decode it back, I get an error: Error: Only 8, 16, 24, or 32 bits supported: 608.

I'm guessing the problem is that there is a "№" character in my certificate parameters, which I think is causing problems when converting to base64 or vice versa.

Can I somehow avoid this problem?

Example:

https://stackblitz.com/edit/vitejs-vite-dmjz3f?file=main.js

    const keys = pki.rsa.generateKeyPair(2048);
    const csr = pki.createCertificationRequest();

    const subject = [
        {
            name: 'commonName',
            value: '"ITEM №1"',
        },
        {
            name: 'countryName',
            value: 'RU',
        },
        {
            name: 'localityName',
            value: 'G SAMARA',
        },
        {
            name: 'organizationName',
            value: '"ITEM №1"',
        },
        {
            name: 'stateOrProvinceName',
            value: 'SAMARSKAIA',
        },
        {
            name: 'emailAddress',
            value: 'test@test.com',
        },
    ];

    const attributes = [
        {
            name: 'extensionRequest',
            extensions: [
                {
                    name: 'keyUsage',
                    digitalSignature: true,
                    nonRepudiation: true,
                    keyEncipherment: true,
                    dataEncipherment: true,
                    keyAgreement: true,
                },
                {
                    name: 'extKeyUsage',
                    clientAuth: true,
                },
            ],
        },
    ];

    csr.publicKey = keys.publicKey;
    csr.setSubject(subject);
    csr.setAttributes(attributes);
    csr.sign(keys.privateKey);

    const rsaPrivateKey = pki.privateKeyToAsn1(keys.privateKey);
    const privateKeyInfo = pki.wrapRsaPrivateKey(rsaPrivateKey);

    const output = {
        privateKey: pki.privateKeyInfoToPem(privateKeyInfo),
        publicKey: pki.publicKeyToPem(keys.publicKey),
        csrKey: pki.certificationRequestToPem(csr), // it's OK
    }

   // decode it
   pki.certificationRequestFromPem(output.csrKey) // Error

const subject = [
  {
    name: "commonName",
    value: '"ITEM №1"',
    valueTagClass: forge.asn1.Type.UTF8,
  },

will fix the error

But this bug still exists: #397
