Convert a char to upper case using regular expressions (EditPad Pro)

I wrote a regular expression in hope that I will be able to replace every match (that is just one char) to upper case char. I am using EditPad Pro (however I am willing to use any other tool that would allow me to do this, as long as it is free to try, since I only need to do this once).

Background: I have a very long text file used by a case sensitive application, and some words start with lower case instead of upper case char, thus crashing the application. This would take very long to do by hand, and it would be quite complicated to do without regular expressions because the occurrence of the (evil) lower case char is very specific.

I have written the select regular expression and now I can use it with a backreference ($1 works just fine) however I can't make it replace with upper case char. I thought something like \u$1 would work, however it doesn't in EditPad Pro.

If no free tool allows me to do this, I guess the alternative would be to just do it in C# however I am in a bit of a hurry and not near a compiler, so I'd have to download the express edition first, so ... It would be preferable to find a tool that supports such a feature!

Thank you!

TextPad will allow you to perform this operation.

example:

test this sentence

Find what: \([^ ]*\) \(.*\) Replace with: \U\1\E \2

the \U will cause all following chars to be upper

the \E will turn off the \U

the result will be:

TEST this sentence

Just an another ussage example for Notepad++ (regular expression search mode)

Find: (g|c|u|d)(et|reate|pdate|elete)_(.)([^\s (]+)
Replace: \U\1\E$2\U\3\E$4

Example:

get_user -> GetUser
create_user -> CreateUser
update_user -> UpdateUser
delete_user -> DeleteUser
