No.  Fields are still delimited by space, and records are still delimited
by newlines.  What has changed is that 'special' characters (space, tab,
newline, hash, backslash) are now escaped within records as octal \NNN.

In the below snippet, I only convert to delimited by \0 *after*
unescaping, when spaces or newlines may be present in the entries.
