Print Chinese(BIG5) text

[ronaldemo]

There are 2 different encodings for Chinese text: GBK (Simplified Chinese) and BIG5 (Traditional Chinese). It is required to allow the developers to define which encoding is used in order to produce correct printing.

Would like to see this patch go through + 1

Two things:

• Can I please get some more information about what model of printer you are using? Example strings you are trying to print are also helpful. This enables finding documentation and keeping test cases for hardware which I don't physically have access to for testing, as otherwise it is very difficult to update the code.
• Passing any encoding name to the intl extension is too broad. I would be happy to ship an enum/restricted selection of Chinese encodings which we map internally to names used by the extension. The issue is that I may need to replace the intl extension one day, and the behaviour is easy to preserve/test if it only does a few things.

I don't particularly remember which printer I was working on for my company back then. Kind of looks like Xprinter XP-S300N

@mike42 I added the ChineseEncoding enum and updated the textChinese method.
