IMHO, TRUNCATE should be remove not only space, but also, tab, CR, LF and so
on, right?

And two or more bytes may express a blank character by some multi-byte
characters encoding system.

For example, in UTF8, one character needs a maximum of 6 bytes.
In UTF16, one character needs 2 bytes fundamentally. However, there is also
a character which needs 4 bytes.

Assuming that a character can be recorded in a byte means spoiling
possibilities.
