FGDB - Error when writing unicode into blob field

I got an SystemError : error return without exception set error when trying to write a unicode into a blob field into a table inside a FGDB using arcpy.da.UpdateCursor with ArcGIS v10.3


for instance:


import arcpy

value = u"a unicode string! with some accent éàèû"
with arcpy.da.UpdateCursor(r"c:\\my_fgdb.fgdb\my_table", ["blob_field"], where_clause="FID = '0') as cursor:
    for row in cursor:
        row[0] = value


I know blob can store string, but is it normal it cannot store unicode?
