Capitalize first letter in custom column

[mhbeyle]

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:

{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.
