Ah, OK ! Sorry for my late reply, but I was studying the haunting problem of the suppression of duplicate lines, without corrupting the order of the file contents :-)) See, below :

https://notepad-plus-plus.org/community/topic/14729/deleting-lines-that-repeat-the-first-15-characters/13

So, let’s consider your example text, below, in a new tab :

{Ausgang
{door
{Eingang}
{Eintritt}
{entry
{exit}
{gate}
{gateway}
{ingress
{Pforte}
{Portal}
{slammer}
{Tor
{Türe}
{Zugang}
Gatter
Tor
Torbogen
Treppen
Stufen
Wände
Gelaender
{banister
{handrail}
{railing}
Innenraum
{interior}

Open the Replace dialog ( Ctrl + H )

Check the Regular expression search mode

SEARCH (?-s)^\{.*[^}\r\n](?=\R)

REPLACE $0}

Click, once, on the Replace All button ( or, successively, on the Replace button )

=> You should get the text :

{Ausgang}
{door}
{Eingang}
{Eintritt}
{entry}
{exit}
{gate}
{gateway}
{ingress}
{Pforte}
{Portal}
{slammer}
{Tor}
{Türe}
{Zugang}
Gatter
Tor
Torbogen
Treppen
Stufen
Wände
Gelaender
{banister}
{handrail}
{railing}
Innenraum
{interior}

Et voilà !

Notes :

• First, the (?-s) modifier forces the regex engine to interpret the special . character as matching a single standard character, only

• Then, the part ^\{ looks the \{ character, at beginning of line ^. Note that the special { regex character have to be escaped !

• Now, the part .* searches any amount, even empty, of standard characters, till …

• A character different from the } character ( part [^}\r\n] ) which is followed by EOL characters ( look-ahead feature (?=\R) )

  • The part [^}\r\n] is a negative character class, looking for any character, different from, either, the } character, the EOL character \r and the EOL character \n

  • The \R stands for any kind of line break ( \r\n, \n or \r )

• In replacement, it rewrites the overall matched string $0, simply followed by the } character

Seemingly, the part, inside your {....} entries, is a range of characters, made up of :

• Normal word character, ( upper or lower-case letter or accentuated one, digit or the low-line character _) => \w

• The dash-minus character -, as, for instance, in the string Basel-Country

• The space character, as, for instance, in the string Northwestern Switzerland

So, the question is : in your present file, which character(s) is/are assumed to be after an unbalanced entry {.... ?

Once, this/these character(s) known ( it may be usual End of Line characters, BTW ), it should be easy to find out the right regex, to get well-balanced entries {....}, again !

You may also insert a small part of your text, in your next post !

Cheers,
