Instead of informing the bell character (hex 07), the example was using
an escaped \ followed by x07.
$ echo \\x07
\x07
$ echo \x07
$ echo \x07 | od -a
0000000 bel nl
0000002
$
* docs: Use \u instead of \\u
Instead of informing the Unicode character 慡, this example was using an
escaped \ followed by u6161.
$ echo \\u6161
\u6161
$ echo \u6161
慡
Before:
$ string escape --style=var 'a1 b2'\\u6161 | string unescape --style=var
a1 b2\u6161
Now:
$ string escape --style=var 'a1 b2'\u6161 | string unescape --style=var
a1 b2慡

Description
|
|
-----------
|
|
|
|
.. BEGIN DESCRIPTION
|
|
|
|
``string split`` splits each STRING on the separator SEP, which can be an empty string. If ``-m`` or ``--max`` is specified, at most MAX splits are done on each STRING. If ``-r`` or ``--right`` is given, splitting is performed right-to-left. This is useful in combination with ``-m`` or ``--max``. With ``-n`` or ``--no-empty``, empty results are excluded from consideration (e.g. ``hello\n\nworld`` would expand to two strings and not three). Exit status: 0 if at least one split was performed, or 1 otherwise.
|
|
|
|
Use ``-f`` or ``--fields`` to print out specific fields. Unless ``--allow-empty`` is used, if a given field does not exist, then the command exits with status 1 and does not print anything.
|
|
|
|
See also the ``--delimiter`` option of the :ref:`read <cmd-read>` command.
|
|
|
|
``string split0`` splits each STRING on the zero byte (NUL). Options are the same as ``string split`` except that no separator is given.
|
|
|
|
``split0`` has the important property that its output is not further split when used in a command substitution, allowing for the command substitution to produce elements containing newlines. This is most useful when used with Unix tools that produce zero bytes, such as ``find -print0`` or ``sort -z``. See split0 examples below.
