parse_ini_file() does not confirm with manual

I have two questions about some quirks in PHP's parse_ini_file().

There are reserved words which must not be used as keys for ini files. These include: null, yes, no, true, false, on, off, none. Values null, off, no and false result in "", and values on, yes and true result in "1", unless INI_SCANNER_TYPED mode is used (as of PHP 5.6.1).

According to the above, you can use no as key if you set INI_SCANNER_TYPED. So why does it fail?

$ echo "no=1" > a.cfg | php -r 'print_r(parse_ini_file("a.cfg", TRUE, INI_SCANNER_TYPED));'
PHP Warning:  syntax error, unexpected BOOL_FALSE in tmp.cfg on line 1
$ php --version
PHP 7.1.14 (cli) (built: Feb  2 2018 08:41:46) ( NTS )

Also, what is the "special meaning" of the characters listed below? The manual does not elaborate.

Characters ?{}|&~!()^" must not be used in the key and have a special meaning in the value.

You misinterpreted the text you quoted. It says:

Values null, off, no and false result in "", and values on, yes and true result in "1", unless INI_SCANNER_TYPED mode is used (as of PHP 5.6.1).

It says about the values. In the default mode, these values are converted to the strings "" and "1". In the INI_SCANNER_TYPED mode, these values are converted to the boolean false and true.

It doesn't say anything about the keys. These words still cannot be used as keys.
