Hi..
Is there a way to capitalize the first field letter in a custom column?
I'd tried it with RegEx in the template of a customize column but I'm not  an expert and I don't know write the expression.
 
I have written this in template field:
	Code:
	{title_sort:re(^([a-z]),\u\1)}
 But I have an "Invalid group reference" error 
 
EDIT: I have read that \u is unsupported by the regex engine, Is this true? Is there another way to capitalize any letter in a custom column?
Regards.
