The wiki says:  
`replace(x,y,z)` returns the string x with all occurrences of string y replaced by string z. Supports multiple parameter pairs y and z.

But in multiple should say 31 or it should be increased. For example:

```auto
$replace(%_filename%,Ó,O,Ú,U,ü,u,Ü,U,ñ,n,Ñ,N,è,e,ê,e,ì,i,î,i,ï,i,à,a,â,a,ò,o,ô,o,ù,u,û,u,ç,c,Ç,C,ß,ss,œ,oe,Œ,OE,ä,a,Ä,A,ë,e,Ë,E,ü,u,Ü,U,ö,o,Ö,O,Â,A)

```

Works fine, but if we add any other pair:

```auto
$replace(%_filename%,á,a,é,e,í,i,ó,o,ú,u,Á,A,É,E,Í,I,Ó,O,Ú,U,ü,u,Ü,U,ñ,n,Ñ,N,è,e,ê,e,ì,i,î,i,ï,i,à,a,â,a,ò,o,ô,o,ù,u,û,u,ç,c,Ç,C,ß,ss,œ,oe,Œ,OE,ä,a,Ä,A,ë,e,Ë,E,ü,u,Ü,U,ö,o,Ö,O,Â,A)

```

It stops workings

Ideally I would like to admit infinite pairs! (With 256/512, we should have enough though), but it not feasible, then please change the wiki to say that it admits a maximum of 31.

Thank you.

4th paragraph:

Note that [characters with special functionality](https://docs.mp3tag.de/format/#characters-with-special-functionality) apply. This implies that you can enclose parameters in `'` to pass them as raw text without parsing. Functions with variable parameter count (e.g., `$replace`) are limited to \< 64 parameters.

You can use several of such `$replace` instructions grouped together in an action group.  
Maybe thats even better to maintain then 1 replace with 256 pairs of items.
