I downloaded the Keyman desktop for the local keyboard/fonts. I would like to encode location names using Tamil/Singhala fonts in the attribute table and then use it to label the map. However, after saving the attribute table with the local fonts, it converts to question marks. Below are the images for before and after saving the table.
If the downloaded fonts are unrecognizable by ArcGIS/QGIS, how do we know which ones can be recognized?
