HI dpcdpc11,
The issue is actually related to your specific WordPress install. I just tested a my localhost install on my end, and I ran into the issue as well.
Inside of wp_config.php, you’ll find a line of code that controls the character set for the data that gets stored in the database. By default, the database is set to utf8.
https://codex.wordpress.org/Editing_wp-config.php#Database_character_set
/** Database Charset to use in creating database tables. */
define('DB_CHARSET', 'utf8');
In my testing, commenting out the above line inside of wp_config.php seemed to resolve the issue on my end, and I was able to save the latin text you provided above.
How to resolve:
1) Locate wp_config.php located in the root of your WordPress install
2) Open that file up, and locate the line similar to:
/** Database Charset to use in creating database tables. */
define('DB_CHARSET', 'utf8');
3) Comment out the above line, by changing it to:
/** Database Charset to use in creating database tables. */
// define('DB_CHARSET', 'utf8');
4) Save the file, and re-test
Please, let us know if that helps resolve things on your end. Things seemed to work well on mine after some testing. IF things work out well, I’ll put together a knowledge base article for future users who may run into this issue.
Thanks,
Evan
