[issue30355] Unicode symbols crash lib2to3.parse

2017-05-19 Thread Terry J. Reedy 

Terry J. Reedy added the comment:

I agree.  Δ is not a 2.x identifier (variable name) or anything else (like 
'binary operator') and it would be wrong for lib2to3.pgen2.parse.classify to 
classify it is such, or as anything else.  So I am closing this.  Benjamin can 
reopen if we are mistaken.

[issue30355] Unicode symbols crash lib2to3.parse

Xiang Zhang added the comment:

Why? Unicode identifiers are not allowed in 2.x. I don't think lib2to3 is able 
or responsible to parse invalid syntax source codes.

[issue30355] Unicode symbols crash lib2to3.parse

2017-05-12 Thread Yann Grisel 

New submission from Yann Grisel:

The code formatter YAPF relies on lib2to3 to parse the code before formatting 
it. The function "classify" from "lib2to3/pgen2/parse.py" returns a ParseError 
when encountering unicode variable names (like Δ), which it should not.
