Error when using a field having a Non-English (Chinese) name in a PlotSegment

[ljhubonog]

When I try to use a field having a non-English (in my case Simplified Chinese) name in my PlotSegment, I get the following error:

This happens whether I drag or select the field for the X or Y axis of a PlotSegment. The diagnostic text is: `

SyntaxError 
    Expected "(", "not", name, operator, value, or variable but "周" found. 
     undefined 

in t

`

If I simply rename the fields to English names in my data source, the bug goes away.

I've tried this in charticulator.com, as well as using Power BI's Charticulator Visual v1.5.0

This problem appears to be similar to the already closed #880, but that fix doesn't address this problem.

As workaround try to use quoted names for columns headers:

"категория"	"значение"
кат1	1
кат2	2

There is issue on parsing expression inside pegjs.
