Question How to add 'Space' to AllowedSelectorChars?

i have a pattern "Room {room number}" which keeps throwing the error:

Code (CSharp):

1. ParsingErrors: The format string has 1 issue:
2. '0x20': There are trailing operators in the selector
3. In: "Room {room number}"

on further investigation the space between room and number seems to be the one causing the error, so i added whitespace to the AllowedSelectorChars
but somehow it doesn't take that into account, is there any special char that needs to be used for whitespace?

 

could it be it was supported in 0.8?
Problem is the system was implemented by a different programmer over a year ago, so i'm having trouble to find where the {room number} comes from... should it be in some string table or set on the prefab or...?

 

ok found it in the localization sheet!
