%(placeholder)s incorrect when translating to Chinese Characters

[JustinWingChungHui]

When converting something like Hello %(placeholder)s

To Chinese becomes: 您好％（占位符）

The % symbol becomes a different Unicode character ％. The ( character also becomes a different Unicode character （ . Also sometimes the s disappears or moves.

And so this unfortunately fails at the compilemessages stage

HI @JustinWingChungHui,

From the description it appears that the bug is related to compilemessages & we can't do much about it.

Although, I would be interested in finding the root cause. It may take some time due to my other commitments.

It happens when it gets put through Google translate. % becomes ％ and ( becomes （ which are different Unicode characters.

You can see what happens if you input %(placeholder)s on the online Google translate site.

So either compilemessages needs to also recognise these two other characters to denote a placeholder or django-autotranslate needs to do something clever (not sure what!) with the placeholder for Asian languages.

Ah! I remember @generalov did some exceptional work & handled it here.

Ran the tests with these strings:

#: test_project/settings.py:16
#, python-format
msgid "Hello %(placeholder)s"
msgstr "你好 %(placeholder)s"

#: test_project/urls.py:27
#, python-format
msgid "Hello %(World)s"
msgstr "你好，世界__"         <---------- 'World' got translated :/

There is definite need for improvement here. :+1: I'll try to work on the issue this weekend.

Meanwhile, a PR is always welcomed :smile:
