Distorted output when using the_title()

[konmavrakis]

I have a post with this title: "This is a test title".

If I use the_title(); the output is:
«This is a test title»

if I echo the title with $post->post_title the output is:
"This is a test title"

Even If I inspect the page, instead of " I see «.

I've also change the font-family to be Arial in order to preclude errors with the font.

I've checked in the_title() and get_the_title() and I can't seem to find anything that could cause the distortion of the output.

The output, top with the_title(), bottom with $post->post_title

Hello @konmavrakis, welcome to WordPress Trac!

This is produced by the wptexturize() function which is hooked into the_title. Take a look at ​https://developer.wordpress.org/reference/functions/wptexturize/ to learn more about what wptexturize() does.
