Blank page after installation

[Bernsnoop]

Hello, tried 3 different installations on different Apache servers and got all the time a blank page. Just turned on the PHP error reporting after research on PHP sites and I think I found the reason. Here's the copy of the PHP error-log :

[01-May-2020 00:57:33 UTC] PHP Fatal error: Uncaught Error: Call to undefined function mb_internal_encoding() in /var/www/html/nubuilder4/nudatabase.php:3
Stack trace:
#0 /var/www/html/nubuilder4/nuchoosesetup.php(21): require_once()
#1 /var/www/html/nubuilder4/index.php(3): require_once('/var/www/html/n...')
#2 {main}
thrown in /var/www/html/nubuilder4/nudatabase.php on line 3

It look like a problem with 3 different .php files. Sorry I'm more familiar with networking and IT structure than with PHP programing. May be PHP packages missing?
I downloaded nuBuilder4-master.zip on GitHub on CentOS server version 8 + MySQL version 8.0.17 + PHP 7.2.11 & Apache 2.4.37

Thanks

Thank you for your fast answer!!
Installed php-mbstring and still have the blank page but with a new error message :

Next PDOException: SQLSTATE[HY000] [2054] The server requested authentication method unknown to the client in /var/www/html/nubuilder4/nudatabase.php:12

In MySQL 8 the default method of authentication has changed, maybe you will need to change something in your server configuration. Another thing you can do is downgrade your MySQL version.
