Problems with liquid include parameters containing non-Western characters

[crandmck]

I ran into a roadblock working on #37. Jekyll/Liquid generates an error when processing includes with non-Western parameter values, e.g.

{% include important.html content="
LoopBackがどのように動くかを理解するには**まずこのページをお読みください。次に、LoopBack
アプリケーションを作成するための基本的な紹介として [Getting started with LoopBack]
(/doc/{{page.lang}}/lb2/Getting-started-with-LoopBack.html)
を参照してください。" %}

The error is:

Liquid Exception: Invalid syntax for include tag. File contains invalid characters or sequences: 
important.html content=" LoopBackがどのように動くかを理解するには**まずこのページをお読みく
ださい。次に、LoopBackアプリケーションを作成するための基本的な紹介として [Getting started 
with LoopBack](/doc/ja/lb2/Getting-started-with-LoopBack.html) Valid syntax: {% include file.ext 
param='value' param2='value' %} in pages/ja/lb2/LoopBack-core-concepts.md

The English content makes extensive use of Liquid includes (with parameters) for alerts and numerous other things. So we need to resolve this or find a workaround, otherwise it's going to be much more difficult to provide translations of the docs.

@Setogit @eddiemonge @cfjedimaster @joesepi Would appreciate any help based on your Jekyll experience. To repro, just copy/paste above into any page in the repo and then follow instructions in the README... Thanks!

I think this is an issue with Liquid. This may be related? Shopify/liquid#31

I'm on my phone so I am not able to test.

Thanks @joesepi This may indeed be the source of the issue. Need to see if we can come up with a workaround, or if we're just hosed. :-(

OK, it turns out that the issue is the liquid variable {{page.lang}} in the include parameter text, not the Chinese characters. Doh!

The good news is that we can move forward with localization plans.
