<![CDATA[Why [A-Z] = [a-z]?]]>I’m trying to replace uppercase characters with “?u”
Lowercase with “?l”, And Numbers with “?d”…
But there is a problem, When I try to replace [A-Z] characters it detect everything as uppercase and replace all of the charecters as"?u", and when I search [a-z] it also detect every character as lowercase and replace them as “?l”

example:

N4eHbZ+HsytYV+dzi3y7UAv3YRqAd5oPJzXnL6QK2d3EvkVu2N1R+BeniJmkY0Z0GGySmDeoVSTxZ7xfJEG5OMDSYEXsOKTOsKT

output for “([A-Z]) & and replace with “?u””

?u4?u?u?u?u+?u?u?u?u?u?u+?u?u?u3?u7?u?u?u3?u?u?u?u?u5?u?u?u?u?u?u?u6?u?u2?u3?u?u?u?u?u2?u1?u+?u?u?u?u?u?u?u?u0?u0?u?u?u?u?u?u?u?u?u?u?u?u?u7?u?u?u?u?u5?u?u?u?u?u?u?u?u?u?u?u?u?u?u?u

aslo the same output for lowecase ([a-z]):

?l4?l?l?l?l+?l?l?l?l?l?l+?l?l?l3?l7?l?l?l3?l?l?l?l?l5?l?l?l?l?l?l?l6?l?l2?l3?l?l?l?l?l2?l1?l+?l?l?l?l?l?l?l?l0?l0?l?l?l?l?l?l?l?l?l?l?l?l?l7?l?l?l?l?l5?l?l?l?l?l?l?l?l?l?l?l?l?l?l?l

So I want to replace uppercase with “?u”, lowercase with “?l” and numbers with “?d” in the previous example.

the expected output should looks like this:
“?u?d?l?u?l?u+?u?l?l?l?u?u+?l?l …etc”

Nah. You’ll hardly even remember it once it sinks to the bottom of the new posting queue. :)

Oh, I see. You just want to replace with a literal ?u. Most questions of this ilk have the poster wanting to convert the case of the matched text.

No, I’m just copying token string of my site, just testing the security level…
Some sites has 1 type of strings that accepted in their system… So if a hacker know how string looks like, He can generate more strings and brute force the website… So this is a danger, I’m fixing it… That’s it

When I try to replace [A-Z] characters it detect everything as uppercase

First problem:
Match-case checkbox?

replace with “?u””

Second problem:
?u is not a valid replace expression.
Have you RTFM?
