+/* |
+ * These maps for ASCII to/from EBCDIC map invariant characters (see utypes.h) |
+ * appropriately for most EBCDIC codepages. |
+ * |
+ * They currently also map most other ASCII graphic characters, |
+ * appropriately for codepages 37 and 1047. |
+ * Exceptions: The characters for []^ have different codes in 37 & 1047. |
+ * Both versions are mapped to ASCII. |
+ * |
+ * ASCII 37 1047 |
+ * [ 5B BA AD |
+ * ] 5D BB BD |
+ * ^ 5E B0 5F |
+ * |
+ * There are no mappings for variant characters from Unicode to EBCDIC. |
+ * |
+ * Currently, C0 control codes are also included in these maps. |
+ * Exceptions: S/390 Open Edition swaps LF and NEL codes compared with other |
+ * EBCDIC platforms; both codes (15 and 25) are mapped to ASCII LF (0A), |
+ * but there is no mapping for ASCII LF back to EBCDIC. |
+ * |
+ * ASCII EBCDIC S/390-OE |
+ * LF 0A 25 15 |
+ * NEL 85 15 25 |
+ * |
+ * The maps below explicitly exclude the variant |
+ * control and graphical characters that are in ASCII-based |
+ * codepages at 0x80 and above. |
+ * "No mapping" is expressed by mapping to a 00 byte. |
+ * |
+ * These tables do not establish a converter or a codepage. |
