Using an apostrophe in a substitution variable

Question

Hello, I have a simple sql plus script which sets a substitution variable and then uses this in an INSERT statement to insert the value of the variable into a database table.
For example:
DEFINE TEXT = 'For full details see PQPs website'
insert into CONSTS(PARAMETER, VALUE, TYPE) values ('admin.marketing.website', '&TEXT1', 'ADMIN');
That's all fine and dandy.
However, I want to put a possessive apostrophe in PQPs, i.e. PQP's but can't find a way that lets me do it and I've tried everything I can think of.
Using the escape character \ doesn't work
i.e.
set escape \
DEFINE TEXT = 'For full details see PQP\'s website'
I just get the string 'For full details see PQP\'
Also using two apostrophes doesn't work either
i.e.
DEFINE TEXT = 'For full details see PQP''s website'
I get the error "ORA-01756: quoted string not properly terminated"
when I try and insert into the database.
I've tried surrounding the value in double quotes etc. and everything I can think of but for the life of me I can't get a string containing an apostrophe into the database using a substitution variable. It must be possible though, isn't it?
Thanks

Could this be a solution ?
TEST@db102 > var text varchar2(50);
TEST@db102 > exec :text := 'For full details see PQP'||chr(39)||'s website';
PL/SQL procedure successfully completed.
TEST@db102 > insert into CONSTS(PARAMETER, VALUE, TYPE) values ('admin.marketing.website', :text, 'ADMIN');
1 row created.
TEST@db102 > select * from consts;
PARAMETER                      VALUE                                              TYPE
admin.marketing.website        For full details see PQP's website                 ADMIN
TEST@db102 >
