320 "Japanese EUC (Extended Unix Code), the standard Japanese encoding in Unix.
|
|
|
321 Equivalent MIME encoding: EUC-JP.
|
|
|
322
|
|
|
323 Japanese EUC was the forefather of all the different EUC's, which all follow
|
|
|
324 a similar structure:
|
|
|
325
|
|
|
326 1. Up to four character sets can be encoded.
|
|
|
327
|
|
|
328 2. This is a non-modal encoding, i.e. it is impossible to set a global state
|
|
|
329 that affects anything more than the directly following character. [Modal
|
|
|
330 encodings typically have escape sequences to change global settings, which
|
|
|
331 affect all the following characters until the setting is turned off.
|
|
|
332 Modal encodings are typically used when it's necessary to support text in
|
|
|
333 a wide variety of character sets and still keep basic ASCII compatibility,
|
|
|
334 or in cases (e.g. sending email) where the allowed characters that can
|
|
|
335 pass the gateway are small and (typically) no high-bit range is available.
|
|
|
336
|
|
|
337 3. The first character set is always ASCII or some national variant of it,
|
|
|
338 and encoded in the standard ASCII position. All characters in all other
|
|
|
339 character sets are encoded entirely using high-half bytes. Therefore,
|
|
|
340 it is safe to scan for ASCII characters, such as '/' to separate path
|
|
|
341 components, in the obvious way.
|
|
|
342
|
|
|
343 4. Each of the other three character sets can be of dimension 1, 2, or 3.
|
|
|
344 A dimension-1 character set contains 96 bytes; a dimension-2 character
|
|
|
345 set contains 96 x 96 bytes; and a dimension-3 character set contains
|
|
|
346 96 x 96 x 96 bytes. 94 instead of 96 as the number of characters per
|
|
|
347 dimension is also supported. Character sets of dimensions 1, 2, and 3
|
|
|
348 use 1-3 bytes, respectively, to encode a character, and each byte is
|
|
|
349 in the range A0-FF (or A1-FE for those with 94 bytes per dimension).
|
|
|
350
|
|
|
351 5. The four character sets encoded in EUC are called G0, G1, G2, and G3.
|
|
|
352 As mentioned earlier, G0 is ASCII or some variant, and encoded into
|
|
|
353 the ASCII positions 00 - 7F. G1 is encoded directly by laying out
|
|
|
354 its bytes. G2 is encoded using an 8E byte followed by the character's
|
|
|
355 bytes. G3 is encoded using an 8F byte followed by the character's bytes."
