    One quick solution is to downgrade your PHP version, assuming you are running on PHP 7.4. Alternatively refer to this URL https://github.com/tecnickcom/TCPDF/pull/123/commits/34eb0dff48eb0b0d5f38f4cfd92ef6d47aefc8b4

    There is a fix for this error with TCPDF

    Run this command:

    sudo nano +1671 /usr/share/php/tcpdf/include/tcpdf_fonts.php

    Add this condition is_numeric($c) in the public method body, so change:

    public static function unichr($c, $unicode=true) {
    if (!$unicode) {
        return chr($c);
    } elseif ($c <= 0x7F) {
        // one byte
        return chr($c);
    } elseif ($c <= 0x7FF) {
        // two bytes
        return chr(0xC0 | $c >> 6).chr(0x80 | $c & 0x3F);
    } elseif ($c <= 0xFFFF) {
        // three bytes
        return chr(0xE0 | $c >> 12).chr(0x80 | $c >> 6 & 0x3F).chr(0x80 | $c & 0x3F);
    } elseif ($c <= 0x10FFFF) {
        // four bytes
        return chr(0xF0 | $c >> 18).chr(0x80 | $c >> 12 & 0x3F).chr(0x80 | $c >> 6 & 0x3F).chr(0x80 | $c & 0x3F);
    } else {
        return '';
    }
}

    To

    public static function unichr($c, $unicode=true) {
    if (is_numeric($c)){
        if (!$unicode) {
            return chr($c);
        } elseif ($c <= 0x7F) {
            // one byte
            return chr($c);
        } elseif ($c <= 0x7FF) {
            // two bytes
            return chr(0xC0 | $c >> 6).chr(0x80 | $c & 0x3F);
        } elseif ($c <= 0xFFFF) {
            // three bytes
            return chr(0xE0 | $c >> 12).chr(0x80 | $c >> 6 & 0x3F).chr(0x80 | $c & 0x3F);
        } elseif ($c <= 0x10FFFF) {
            // four bytes
            return chr(0xF0 | $c >> 18).chr(0x80 | $c >> 12 & 0x3F).chr(0x80 | $c >> 6 & 0x3F).chr(0x80 | $c & 0x3F);
        } else {
            return '';
        }
    }
}
