binaryDecode in LC 7.0(rc2) and EXIFLib

[FlexibleLearning.com]

LC v7 should be backwards compatible. I suggest you submit this in a bug
report, especially if you can identify the specific function(s)/keyword(s)
used by formatsList where different data is returned in order to help the
team locate the issue. I suspect it will be something to do with how Unicode
is now handled.
