Selecting only normal character data from column

Question

Hi,
We have a table column which stores party names and this could consist of non english characters. Would anyone know how do we just select regular english character rows from the table using a select query and not include the rows which have non-english characters?
Thanks

There iare two points with the suggestion by Frank.
First i think he missed an +
and secondly it doesnt work for example with german umlauts.
with data as (
select 'SERPI!! GAB' s from dual union all
select 'SE£ GRA' from dual union all
select 'ARA%%& sa' from dual union all
select 'dasssädsa' from dual union all
select 'ara€ ssa' from dual union all
select 'gabriele dsa' from dual
SELECT     *
FROM     data
WHERE     REGEXP_LIKE ( s
              , '^[A-Za-z]+$'
no rwos selected
with data as (
select 'SERPI!! GAB' s from dual union all
select 'SE£ GRA' from dual union all
select 'ARA%%& sa' from dual union all
select 'dasssadsa' from dual union all
select 'ara€ ssa' from dual union all
select 'gabriele dsa' from dual
SELECT     *
FROM     data
WHERE     REGEXP_LIKE ( s
              , '^[A-Za-z]+$'
S
dasssadsa
(without umlaut)
so perhaps you will give translate a try e.g.
with data as (
select 'SERPI!! GAB' s from dual union all
select 'SE£ GRA' from dual union all
select 'ARA%%& sa' from dual union all
select '@dass äsadsa' from dual union all
select 'ara€ ssa' from dual union all
select 'gabriele dsa' from dual
select s
,  translate(
    lower(s)
    ,'@abcdefghijklmnopqrstuvwxyz1234567890 '
  ) t
from data
where
length(
  translate(
    lower(s)
    ,'@abcdefghijklmnopqrstuvwxyz1234567890 '
< length(s)
S T
SERPI!! GAB !!
SE£ GRA £
ARA%%& sa %%&
@dass äsadsa @ä
ara€ ssa € porjection is just for explanation purpose
