Please read this:

This article says that a regression was introduced by security update
961371. The regression imposes an artificial 2,500 character length
limitation on strings that are contained in OpenType or TrueType fonts.
They mean 2.5K Unicode characters, or 5000 bytes.

A subsequent security update, 972270, has restored the character length
limitation for individual strings to 64 KB (32,768 Unicode characters),
matching the OpenType specification.

Carry on embedding!
