Tables with multibyte characters and ASCII are not aligned properly after
org-table-align in GUI mode.

In -nw mode table is properly aligned, but its incorrect in GUI mode.

Steps to reproduce:
Start emacs in GUI mode. Copy and paste table below to org-mode buffer. Put
emacs cursor inside the table, run org-table-align, all columns should be
aligned properly, but they don't. Save buffer in file. Open the same file
in no-GUI mode, the table will be properly aligned.
