Strange characters on MySQL Point column

I have a POINT column to store coordinates, and here is my insert query:

INSERT INTO _coordinates_test (coordinates) VALUES(POINT(59.356125477261266, -2.8759361517393898))

But here is what i get on the column (coordinates):

   …•­M@“Ö(ÐêÀ

I also tried reading coordinates like this:

SELECT POINT(59.356125477261266, -2.8759361517393898)

I also tried converting a regular coordinates string to a POINT, like this:

SELECT ST_PointFromText(CONCAT('POINT(', '59.356125477261266 -2.8759361517393898' , ')'))

Here is the CREATE TABLE query:

CREATE TABLE `_coordinates_test` (
    `coordinates` POINT NULL DEFAULT NULL
)
COLLATE='utf8mb4_unicode_ci'
ENGINE=InnoDB
;

The result is always the same, those strange characters.

Is there some issue with the encoding (currently utf8mb4_unicode_ci) or does POINT not support coordinates ?

Could it be that my MySQL Client software (HeidiSQL) is not reading the data correctly ?

MY USE CASE: Im trying to store coordinates in that column so i can calculate the distance (in meters) between different physical objects.
