SQL LOAD FILE fills table with zeros/null values - php

Question

So, I have an issue with loading my CSV into SQL database with PHP and Wordpress. Both are running on local xammp atm.
This is my code for loading the CSV file. It first uploads it via html form to some temp folder (data) and then tries with LOAD DATA to copy the content into the table (wp_data)
<?php
if (isset($_POST['submit'])) {
global $wordpress,$wpdb;
$file = $_FILES['fileToUpload']['tmp_name'];
$target_dir = $_SERVER['DOCUMENT_ROOT']."/data";
$target_file = $target_dir . '/' . basename($_FILES["fileToUpload"]["name"]);
move_uploaded_file($file, $target_file);
$sql="
LOAD DATA INFILE '$target_file' INTO TABLE wp_data FIELDS TERMINATED BY ';' IGNORE 1 ROWS";
$query = $wpdb->query($sql);
}
?>
The uploading part works fine, however when it tries to fill the table with the data, it just fills "0s"/NULL values, like this:
The file as text looks like this:
And visually, it looks like this:
Table structure from SHOW CREATE TABLE wp_data:
CREATE TABLE `wp_data` (
`Unix_time` int(11) NOT NULL,
`Message` text NOT NULL,
`Time` float NOT NULL,
`DF` int(11) NOT NULL,
`Type_code/BDS_number` int(11) NOT NULL,
`Latitude` double NOT NULL,
`Longitude` double NOT NULL,
`Altitude` int(11) NOT NULL,
`Ground_speed` double NOT NULL,
`Baro_diff` int(11) NOT NULL,
`Heading` int(11) NOT NULL,
`TAS` int(11) NOT NULL,
`Mach` float NOT NULL,
`FOM_SOURCE` varchar(40) DEFAULT NULL,
`Wind_speed` varchar(40) DEFAULT NULL,
`Wind_direction` varchar(40) DEFAULT NULL,
`Temperture` text,
`Pressure` varchar(40) DEFAULT NULL,
`Turbulence` varchar(40) DEFAULT NULL,
`Humidity` varchar(40) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1
What am I doing wrong here? I am quite new at PHP and got stuck on this
:(...
Thx.

Fixed it by setting the encoding in query to CHARACTER SET UTF8 like this:
LOAD DATA INFILE '$target_file'
INTO TABLE wp_data
CHARACTER SET UTF8
FIELDS TERMINATED BY ';'
IGNORE 1 ROWS;
