Steps to reproduce:

Launch `emacs -Q`, paste these = four lines on a buffer

aaaaaaaaa'aaaaaaaaaaaaaaaaaaaaaaaaaaaa aa= aa'aaaaaaaaaaaaaaaaaaa'aaaaaaaaaa
aaaaaaaaa=E2=80=99aaaaaaaaaaaa= aaaaaaaaaaaaaaaa aaaa=E2=80=99aaaaaaaaaaaaaaaaaaa=E2=80=99aaaaaaaaaa
nnnnnnnnn'nnnnnnnnnnnnnnnnnnnnnnnnnnnn nnnn'nnnnnnnnnnnnnnnnnnn= 9;nnnnnnnnnn
nnnnnnnnn=E2=80=99nnnnnnnnnnnnnnnnnnnnnnnnnnnn nnnn=E2=80= =99nnnnnnnnnnnnnnnnnnn=E2=80=99nnnnnnnnnn

Search for the first one w= ith char folding enabled. In my system Emacs
doesn=E2=80=99t match the s= econd line. It matches after I hit =E2=80=98C-M-d=E2=80=99 to
delete the= last character from the search query.

If you search with char foldi= ng enabled for the third line then it
does match the fourth, even though= the third and the fourth lines are
just copies of the first two with th= e a=E2=80=99s replaced by n=E2=80=99s.

All the best,=
Andrea

Please note that when the search string is too long for char folding, then it displays the message at the end of the Isearch prompt before disabling char folding: "Too many words; switched to literal mode" Char folding is regexp-based and converts the search string into a very long regexp that matches all character variants. But the regexp have limitations when matching runs out of internal stack space. This is described in the Info node: (info "(elisp) Regexp Problems") For example, my stack is longer than yours, so the second line of the described case matches with line length of 74 characters. But the search still switches to literal mode on 87 characters.

Indeed, thanks for pointing to the version number 27.2. That message was added in 28.1. And also the regexp stack size was increased too in 28.1. And the new node exists also only in 28.1. So unless someone has an idea how to implement the search for regexps of arbitrary lengths, this report could be closed.

Right, it's possible to customize char-fold-exclude to make the string longer. As for how to do this without customization, internally maybe it would be possible to add regexp back references to reuse parts of the previous regexps constructed for the same letter.

We already have a variable ‘char-fold-include’ that adds equivalence sets, so maybe it would be sufficient to add just a new boolean variable, maybe with a name e.g. ‘char-fold-override’. When customized to non-nil, it will prevent from filling ‘char-fold-table’ with default equivalence sets. Thus it will build equivalence sets from zero using ‘char-fold-include’ only, like you need to do.

My reading of this is that the feature by default will not work at all: since the default value is not nil, the doc string says that I "start with an empty table", so no folding will happen. Is that what you meant? And if so, how isn't this a change in behavior? In Emacs 27 the folding works by default and finds equivalent characters without any user intervention. What am I missing?
