bug : "Failed to parse time string" if the date string contains Chinese language character

[joomlagate]

Steps to reproduce the issue

in any Joomla language file (ini format) , write some Chinese language character in the date string after the comment symbol like:

; @date 三 2013

Expected result

com_localise will ignore anything it can not parse in "comments" and go on to open that language file for editing.

Actual result

com_localise refuse to open that language file and return a warning message:

0 DateTime::__construct(): Failed to parse time string (三 2013) at position 0 (�): Unexpected character

System information (as much as possible)

Joomla v3.6.5
com_localise v4.0.29 dev
PHP 7.0

Additional comments

I think, "comment" is comment, it is not CODE. Why com_localise will treat comment contents as normal code? If com_localise can not understand the Chinese language in date string ( which in fact is in comment line), just skip it, and go on to open that file. Because, we use com_localise to check real language keys , not comments.

Thank you.
