unescape chars like "_x0020_"
Created originally on Bitbucket by arnaugil126 (Arnau Gil)
I have some xlsx files which contain chars like
_x0020_, which is the escaped value for
" " (empty string) in SharePoint.
xlrd unescape these values to get the original chars using this function https://github.com/python-excel/xlrd/blob/bbccdcb96e40b590d71ed14682237bea1e8f1dc5/xlrd/xlsx.py#L136
Could we do the same in openpyxl?
