folding a string

is there any otherway to break into 80 byte per line with putting a line break...
As fold does not fit in the current schema .

here is the document which says


breaking the lines to have a maximum of width column positions
(or bytes, if the -b option is specified). The fold command breaks
lines by inserting a newline character so that each output line is the
maximum width possible that does not exceed the specified number of
column positions (or bytes).
A line cannot be broken in the middle of
a character. If no files are specified or if a file name of - is
specified, the standard input is used.

NAME
fold -- fold long lines for finite width output device SYNOPSIS
fold [-bs] [-w width] [file ...] DESCRIPTION
The fold utility is a filter which folds the contents of the specified files, or the standard input if no files are specified, breaking the lines to have a maximum of 80 columns. The options are as follows: -b Count width in bytes rather than column positions. -s Fold line after the last blank character within the first width column positions (or bytes). -w width Specify a line width to use instead of the default 80 columns. The width value should be a multiple of 8 if tabs are present, or the tabs should be expanded using expand(1) before using fold. ENVIRONMENT
The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of fold as described in environ(7). SEE ALSO
expand(1), fmt(1) STANDARDS
The fold utility conforms to IEEE Std 1003.1-2001 (``POSIX.1''). BUGS
If underlining (see ul(1)) is present it may be messed up by folding. BSD
