Answer 1

you can use

^(?![a-zA-Z,.']+$).+$\R?

The regular expression matches any non-empty string ( .+), which does not consist of ASCII letters ,, .or '. \R?at the end there is an optional line break.

More details

• ^ - beginning of line
• (?![a-zA-Z,.']+$) - , , : [a-zA-Z,.']+ - 1 ASCII-, , ($)
• .+ - 1 + , char
• $ -
• \R? - char ()

Answer 2

:

: ^.*[^a-zA-Z.,'].*$
: ``

:

• .*
• [^...]
• .*
• ^...$

, \r?\n $. I.e.: ^.*[^a-zA-Z.,'].*\r?\n

Answer 3

Try replacing all this matching

^.+?[^a-zA-Z,.'\r\n]+(.|\r?\n)
