By definition, text files meet all of the following requirements:
the file does not contain any NUL characters,
every line in the file is terminated by a <newline> character, and
no line in the file (including the terminating <newline> character) contains more than LINE_MAX bytes.
On many systems, LINE_MAX is 2048. The value on your system can be determined using the command:
The message you are getting probably indicates that the file you are trying to edit is not a text file because it violates requirement #3 in the list above.
If you want to split long lines in a file into shorter, adjacent lines that meet the requirements of a text file, try using the fold utility. If you want to split long lines into segmented files where one file contains the 1st X characters from each line from an input file and another file contains the X+1st through the 2Xth character from each line from an input file, etc.; try using the cut utility.
Without knowing more about the format and contents of the file you are trying to edit and the changes you want to make to that file, it is hard to suggest anything more specific.

fold
fold(1) User Commands fold(1)NAME
fold - filter for folding lines
SYNOPSIS
fold [-bs] [-w width | -width] [file]...
DESCRIPTION
The fold utility is a filter that will fold lines from its input files, breaking the lines to have a maximum of width column positions (or
bytes, if the -b option is specified). Lines will be broken by the insertion of a NEWLINE character such that each output line (referred to
later in this section as a segment) is the maximum width possible that does not exceed the specified number of column positions (or bytes).
A line will not be broken in the middle of a character. The behavior is undefined if width is less than the number of columns any single
character in the input would occupy.
If the CARRIAGE-RETURN, BACKSPACE, or TAB characters are encountered in the input, and the -b option is not specified, they will be treated
specially:
BACKSPACE The current count of line width will be decremented by one, although the count never will become negative. fold will
not insert a NEWLINE character immediately before or after any BACKSPACE character.
CARRIAGE-RETURN The current count of line width will be set to 0. fold will not insert a NEWLINE character immediately before or after
any CARRIAGE-RETURN character.
TAB Each TAB character encountered will advance the column position pointer to the next tab stop. Tab stops will be at each
column position n such that n modulo 8 equals 1.
OPTIONS
The following options are supported:
-b Counts width in bytes rather than column positions.
-s If a segment of a line contains a blank character within the first width column positions (or bytes), breaks the line
after the last such blank character meeting the width constraints. If there is no blank character meeting the require-
ments, the -s option will have no effect for that output segment of the input line.
-w width|-width Specifies the maximum line length, in column positions (or bytes if -b is specified). If width is not a positive deci-
mal number, an error is returned. The default value is 80.
OPERANDS
The following operand is supported:
file A path name of a text file to be folded. If no file operands are specified, the standard input will be used.
EXAMPLES
Example 1 Submitting a file of possibly long lines to the line printer
An example invocation that submits a file of possibly long lines to the line printer (under the assumption that the user knows the line
width of the printer to be assigned by lp(1)):
example% fold -w 132 bigfile | lp
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of fold: LANG, LC_ALL, LC_CTYPE, LC_MES-
SAGES, and NLSPATH.
EXIT STATUS
The following exit values are returned:
0 All input files were processed successfully.
>0 An error occurred.

fold and cut(1) can be used to create text files out of files with arbitrary line lengths. fold should be used when the contents of long
lines need to be kept contiguous. cut should be used when the number of lines (or records) needs to remain constant.
fold is frequently used to send text files to line printers that truncate, rather than fold, lines wider than the printer is able to print
(usually 80 or 132 column positions).
fold may not work correctly if underlining is present.
