Bug report

Consider the code below:

d = {    "ó": {        "á": {            "í": {                "theta": 1            }        }    }}try:    result = d["ó"]["á"]["í"]["beta"]except:    import traceback;traceback.print_exc()

The output provided is:

Traceback (most recent call last):  File "W:\pydev.debugger\check\snippet2.py", line 12, in <module>    result = d["ó"]["á"]["í"]["beta"]             ~~~~~~~~~~~~~~~~~~~^^^^^^^^KeyError: 'beta'

Notice that for each additional unicode char, an additional `~' is added.

This seems to happen because when computing the anchors intraceback._extract_caret_anchors_from_line_segment the columns from the ast nodes generated inast.parse seem to be related to bytes and not actual chars.
