Regular Expressions and Special Characters

[Fishface]

... The business have said that if the character is the same without any accent, then that's OK by them - so if one system says "n" and the other says "ñ" then they want that to match.

So, I was hoping to do a regular expression replace on the text in both tables to replace "ñ" with "n" in both systems, and the same for a,e,i,o,u etc. etc.

Apart from going through a character map, does anyone know of a regular expression syntax that I can use to do the replacement?

Careful, año and ano do not match.

E.g that guy in the business is a real ano.

2014 is going to be a great año

It doesn't. The ajax request goes to h ttp://forums.contractoruk.com/thanks.php

Edit: Ah, you mean they're loading jQuery from the CDN.

Thanks

We should have a button that doesn't need ajax.googleapis.com for that....

... although a pint would be equally acceptable.

It wasn't THAT helpful

Have a instead.

Is this Oracle?

Thanks - there's some things in there that I might need to plug into my code.

Would in not be better to find all the accented letters? And replace those or add them to your regex

A simple regex will do that.

That's one way to do it, but I was wondering if there was a standard way to do it - for example, Oracle has a [:punct:] option which will remove all punctuation.

At the moment, I've gone looking for special characters, but since we are multi-muilti-lingual, there are lots of characters that I could expect, and if I've missed one then I'll need to make more changes to add in extra characters.

If you're using (or could use) an up to date build of PERL you can use Unicode::Normalize to do it for you

Unicode::Normalize - perldoc.perl.org

In fact any language that explicitly supports Unicode should have a Normalization module available

What language are you using? The term you need to google is diacritics.

Does anyone know of an easy way to use regular expressions to replace special characters?

I'm trying to compare data from two tables to see where there are discrepancies, but a lot of them contain special characters. The business have said that if the character is the same without any accent, then that's OK by them - so if one system says "n" and the other says "ñ" then they want that to match.

So, I was hoping to do a regular expression replace on the text in both tables to replace "ñ" with "n" in both systems, and the same for a,e,i,o,u etc. etc.
