Re: Help with RegEx?

I have reduced my requirements to just matching input that contains the 
letters "i n t u o" in that order even if interspersed with other
characters. 


The RE I worked out is:

     [Ii].*[Nn].*[Tt].*[Uu].*[Oo]

Thanks to all who helped me come to this result. 

I also need to match input that exceeds 50 characters. I tried several
REs, 
paring it down, eventually, to:

     .{50}

It doesn't work. 

This seems like it should be pretty simple, but it's not working. It works
in 
regextester.com's tester, but it isn't working for me. Is there a simpler
(or 
different) way to check for input length? (I presume that my "flavor" of 
regex interpreter isn't accepting this form...)

Thanks for your help.
