Unicode not supported for Column access to TableWS

[DanielMurphy22]

Original reporter: [ISIS]/[James Lord]

This is something that should be fixed automatically when we move to Python 3.

Expected behavior

Can access a table column as a list with the syntax MyTable.column[“Column header”], even if writing code that is Python 3 compatible

Actual behavior

TypeError: No registered converter was able to produce a C++ rvalue of type int from this Python object of type unicode
  File "<string>", line 14, in <module>

Steps to reproduce the behavior

Create a table (for example a results table from Muon Analysis)
Open a new script tab in Workbench. Add the following after the standard headers (change the actual table and column names as appropriate):

tab=mtd["ResultsTable"]
colY=tab.column("workspace_name")
print (colY)

Note that removing the “unicode_literals” from the future statement makes the script work as intended.

Platforms affected

Workbench 4.2

This is no longer an issue with Python 3 as Boost.Python knows how to deal with unicode automatically.
