OK, so I have installed Pharo 9.0 with the M1 VM and everything is nice and quick. I am porting my code across and I have a problem that involves STON Reader. I use this to convert my objects for storage in my text based database. I canât run my code because STON Reader fails when reading in one of the objects. The contents are as follows: "{#entryName:'PAYPAL *COSYFEET',#entryDate:Date['2021-01-25Z'],#transactionID:'202101250001',#entryAmount:-5041216832887849/140737488355328s8,#entryCategory:nil,#entryDescription:'35314369001 GB , 5959 22JAN21',#match:'Nâ}â The errors is this: Character 122 is at the conjunction of the 4 and 9 in the ewntryAmount: 5041216832887849/140737488355328s8, Any help on this would be great. I have a few thousand entries to fix if there is a problem with the file (although my code works fine with this file under 8.0) David Pennington
