I have a list of about 1,300 IKEA products - this is an example of some of them:

```
läkt
bigarrå
bekväm
blixt
block
blom
bärbar
bärby
bästis
bådalen
bågvik

```

I'm trying to use a RegEx to mark those which contain "special" characters - e.g. anything other than simple lowercase a to lowercase z - such as:

```
läkt
bigarrå
bekväm
bärbar
bärby
bästis
bådalen
bågvik

```

I tried this one:

```
[^a-z]

```

But it selects all of the words.

I could do it if I were just using PHP, via the `ctype_alnum` function, but here I'm just using the TextPad or NotePad++ text editors.

Is there any way to achieve this using a standard RegEx?
