The length of a hankaku katakana string is always represented in bytes, at both the workstation and the mainframe. A hankaku katakana character occupies one byte, except in eucjis.
The eucjis hankaku katakana character set uses an indicator (SS2) in character-type strings to announce that the next byte is occupied by a hankaku katakana. The SS2 indicator occupies one byte, and the hankaku katakana itself occupies one byte. As a result, the total length of each eucjis hankaku katakana character is two bytes.
