Hello, @pan-jan and All,

Try this regex S/R :

SEARCH (?i)\bMc([[:alpha:]])

REPLACE Mc\u$1

which changes any form, as below :

mcDonalds
McDonalds
mCDonalds
MCDonalds
mcdonalds
Mcdonalds
mCdonalds
MCdonalds

with the unique good syntax :

McDonalds

Notes :

The (?i) in-line modifier carries the search in an insensitive way
The [[:alpha:]] POSIX class range represents any single uppercase or lowercase letter
In replacement, the \u syntax rewrites the next letter, stored in group 1, in uppercase

the \u syntax

just the

\u

syntax doesn’t work

Hello @pan-jan and All,

I’m really sorry but the regex syntax \u, in replacement, does do the job ! That is to say it capitalizes the first letter of the following string or group !

For instance :

SEARCH (?-i)foo

REPLACE \ubar

changes the word foo, with this exact case, by Bar

And :

SEARCH (?-i)(foo|bar)

REPLACE \u$1

would change the words foo and bar , with this exact case, by the words Foo and Bar

Best Regards,

maybe you missed @PeterJones comment and OPs info?

I’m using a different editor, and RegEx doesn’t use \u or \l there

Hi @ekopalyse,

Ah… OK. So, what’s he waiting for to switch to Notepad++ ;-)))

Thank you but…
AkelPad is much better than Notepad ++.

Hi, @pan-jan,

If so, why don’t you join the Akelpad community and find out a solution, from within this software, or, may be, ask the Akelpad’s author to improve the regex engine ?

I asked before.
No response means nothing can be done.

I see there are some good RegEx specialists here
and I’m trying to solve the problem here.

Implementation of regex varies from one application to the next.

It’s a guess based on the OP’s results but it seems that \u in the OP’s editor is the lead-in for Unicode related stuff such as \u0025 for a percent (%) sign. The OP’s examples have \xFFFF characters in them.

Fiddling with people’s names seems dangerous as there are people who have Mc… style surnames where the third character is not upper-case. If there is a requirement to make the names a consistent case then convert everything to upper case.

I think we are in https://community.notepad-plus-plus.org/topic/15958/faq-desk-you-ve-asked-your-question-in-the-wrong-place territory.
