Android 8.1 自定义热点的时候设置了热点maxLength="32"，但是在希伯来语等状态下还是发现在没到32个字符之前就无法把热点设置成功了

    <Preference
        android:key="hotspot_settings"
        android:title="@string/hotspot_preference_title"
        android:fragment="com.sprd.settings.wifi.HotspotSettings" />

        mSsid.addTextChangedListener(this);
        mPassword.addTextChangedListener(this);

    public void afterTextChanged(Editable editable) {
        validate();
    }

    private void validate() {
        String mSsidString = mSsid.getText().toString();
        if ((mSsid != null && mSsid.length() == 0)
                || ((mSecurityTypeIndex == WPA2_INDEX || mSecurityTypeIndex == WPA_INDEX) && mPassword.length() < 8)
                || (mSsid != null &&
                Charset.forName("UTF-8").encode(mSsidString).limit() > 32)) {
            getButton(BUTTON_SUBMIT).setEnabled(false);
        } else {
            getButton(BUTTON_SUBMIT).setEnabled(true);
        }
    }
