1.
I want to replace "\{[\s\S]+?\}" with "".
"\{[\s\S]+?\}" can match multi-line text even when "Regular Expressions Can Match New Line Characters" option is off, if I use Replace Next.
But when using Replace All, that option has to be enabled.
Is this by design?



2.
For example, if I want to replace something with "\x{2030}\n", the Replace with text has to be "\x{2030}\\n" or "\x2030\\\n".

Escape sequences are always on when searching from the command line.
But when I want to search a single "\" from the command line, I have to use "\\\\", not "\\".
