"&40" &41" Symbols appearing in API documentation, meaningful or a glitch?

I only just started noticing these within the past month I believe, do these mean something im not familiar with or is it an issue with their online documentation system? For instance, in the 5.3 reference for AAIController::RunBehaviorTree the example shows:

virtual bool RunBehaviorTree  
&40;  
    UBehaviorTree &42; BTAsset  
&41;

If it is a glitch it is interesting that they havent fixed in the past month or so. And conversely if it is some hip new programming thing please school me, I am eager to learn :nerd_face:

these are supposed to be ASCII codes. I think their documentation might be bugged.

&40; is (
&41; is )
&42; is *

so your screenshot should look like:

virtual bool RunBehaviorTree
(
UBehaviorTree * BTAsset
)

This was found solely in the UE 4.27 version of the API C++ reference, which is a bummer. The UE 5.5 version is accurate.

I am sorry, I was wrong. Only UE 5.5 and UE 5.4 versions of C++ API reference are correct. All other versions (UE 5.3, UE 5.2, UE 5.1, UE 5.0, and UE 4.27) have the same issue.
