0x00–0x7F) are used otherwise. Names used specifically for the 7-bit Roman set include "JISCII", "JIS Roman", "ISO646-JP", "JIS C6220-1969-ro", "Japanese-Roman", "Japan 7-Bit Latin", and "ISO-IR-14", whereas names used specifically for the 7-bit Kana set include "ISO-IR-13", "JIS C6220-1969-jp" and "x0201-7". The substitution of the yen symbol for backslash can make paths on DOS and Windows-based computers with Japanese support display strangely, like "C:¥Program Files¥", for example. Another similar problem is C programming language's control characters of string literals, like printf("Hello, world.¥n");. Codepage layout The following table is the original 8-bit coded character set of JIS X 0201 (with the kana set indicated by bytes with the high bit set). As part of Shift JIS Following is the mapping used for JIS X 0201 as part of Shift JIS, i.e. showing the 8-bit form of JIS X 0201, and mapping the Katakana characters to the Halfwidth and Fullwidth Forms block (which in turn derives its half width kana layout from JIS X 0201). Alternative mapping of katakana The basic ISO-2022-JP profile does not permit the Kana set of JIS X 0201, only the Roman set and JIS X 0208 (although ISO 2022 / JIS X 0202 itself permits it). Accordingly, when converting JIS X 0201 katakana (or Unicode half-width kana, which use the same layout) to ISO-2022-JP, the following mapping or transformation is often used. This allows the kana to be converted to JIS X 0208. In theory, this mapping is equally correct, as JIS X 0201 itself does not specify display width, although in practice (and especially in duospaced environments) JIS X 0201 is used for half-width katakana. For ease of comparison with the chart above, the mapping is shown below over the JIS X 0201 katakana encoding and with the high bit set. Variants and extensions Shift JIS IBM's implementations Code page 897 is IBM's implementation of the 8-bit form of JIS X 0201. It includes several additional graphical characters in the C0 control characters area, and the code points in question may be used as control characters or graphical characters depending on the context, similarly in concept to OEM-US, but with different graphical characters. The C0 rows are shown below. IBM also designate pure 8-bit JIS X 0201 without these control code replacements as Code page 1139. Another variant, including a smaller subset of these C0 replacement graphics (including only the box drawing characters in 0x01–06, 0x11, 0x15–17
