Hi,

Because, Unicode UTF-16 character encoding must be used, and each character uses 2 bytes.

If longer than 70 Unicode characters, segmentation headers must be added to allow the receiver to reassemble. These headers are 6 bytes or the size of 3 UTF-16 characters, which leaves space for 67 Unicode characters per long message segment.

As stated above, 67 Unicode characters per long message segment.

2 x 67 = 134

No, that setting is not at all related.
