Terminal v1.0.1401.0

Steps to reproduce

Write the following string to the terminal (Python):

>>> print("│\x1b[33m\U0001F862\x1b[0m│")

This string is a unicode box char, followed by a foreground yellow escape, a unicode arrow, a reset escape, and another box character.

Expected behavior

The string should render three characters: a vertical line, yellow arrow, vertical line.

Actual behavior

There is an extra space after the arrow.

Note that this only occurs with that particular unicode character. If I replace that unicode arrow with any other character then it renders as expected.
