FlavorText.xml error on game startup

Hi, I have the following error on game startup, and each time I try to reload a game too.

"...\My Games\GalCiv4\Factions\FlavorText\_23300E1E9E76447F83936856068CE620_FlavorText.xml(594,48): error:
invalid character 0x1F"

I validated my game files with Steam, but it keeps happening. It started doing that after a crash.

I've checked the file, but there's a lot of lines, so it's a little like looking at a needle in a haystack.

How can I find that invalid character?

 

I thought it could mean line 594, so here it is:

<Text><![CDATA[The stars are ours to conquer, ! Prepare for subjugation or annihilation, your choice.]]></Text>

 

Edit:

Weird, I can't copy/paste the text.
Here is the image:
