[Qgis-user] custom string formatting for grid coordinate labels

[Neumann, Andreas]

Hi Andrew, 

Thank you for these useful custom expression functions.   

It would be quite useful to have the Python unichr() function available
in QGIS as an expression function under the "String" functions group. 

Thanks and greetings, 

Andreas
