Error: "Unknown code" in dockscreens

[Heliogenesis]

It appears that using scrSetDesc in the canvas block of a dockscreen in 1.3 final causes errors if there is a "\n" (newline) at the beginning of the desc in scrSetDesc. It doesn't throw an error per se (that is, no message is written to the debug log), but instead shows some yellow text saying "Unknown code: X" as the screen's description instead of whatever I put in scrSetDesc.

I'm not sure if this is a bug, or simply me failing to rtfm.

TO REPLICATE: Copy and paste the following code into an xml file in your extensions folder (or download the attached file), and then start a new game in debug mode while loading this extension. Open debug console, and type in "(heligen_unknownCodeErr)" without the quotes.

Code: Select all

<?xml version="1.0" ?>
<!DOCTYPE TranscendenceExtension
	[	
	<!ENTITY heligen_dbg_UnknownCodeErr				"0xDEFDDB00">

Can you try (scrSetDesc gScreen (cat "\n If you're seeing this, then you're probably not running 1.3 final."))

[Heliogenesis]

Using (scrSetDesc gScreen (cat "\n If you're seeing this, then you're probably not running 1.3 final.")) in the canvas resulted in an "Unknown code" error (to be exact, "Unknown code: n."). Placing this in <OnPaneInit> resulted in the same thing, and so does running this command in an action or in the debug console.

Running the command without the space between "\n" and "I":
(scrSetDesc gScreen (cat "\nIf you're seeing this, then you're probably not running 1.3 final."))
from the debug console resulted in a similar "error" (no debug log, and showing on the dockscreen in yellow text): "Invalid code terminator".

Placing the "\n" at the end or the middle of the string produces no problems, and functions as expected.
