You can sometimes save some memory in these sort of "flyweight" records by moving all the strings in a group into a string table. Make one byte-array buffer for the text from multiple records, then use a ("small") offset integer in each record to refer to the starting position of strings within the string table. Rather than using a 64 bit pointer, or an inline array of max-size, for each string, just use perhaps a 16 bit offset into the table for each string. (or 32 bit if you expect enough data). Of course, this also requires wrapper setter/getter type code, but it can be a good trade to save space.
