Hi Emir,
So this would likely be different from what the operating system counts, as
the operating system may consider each Chinese characters as 3 to 4 bytes.
Which is probably why I could not find any record with subject:/.{255,}.*/
Is there other tools that we can use to query the length for data that are
already indexed which are not in the standard English language? (Eg:
Chinese, Japanese, etc)
Regards,
Edwin
