21 * The table below lists codepages that are supposed to have roundtrip mappings for
22 * the U+20AC Euro sign.
23 *
24 * Changes made 2000nov28 and marked as such are due to the following:
25 *
26 * After updating all ibm-*.ucm files with precise fallback indicators (|0, |1, |3),
27 * some of these codepages failed the Euro regression test.
28 * This means that the actuall mappings changed when only the preciseness of fallback
29 * mappings should have changed.
30 * My (Markus) suspicion is that some files got Euro sign mappings added manually,
31 * changing their contents compared to the NLTC (IBM Toronto codepage database) definition.
32 * Such changes are highly undesirable because they effectively define new codepages.
33 * Codepage mapping files with "ibm-*.ucm" should always exactly match the files
34 * from the IBM codepage database.
35 * (If there are several mappings with the same number, then we choose the
36 * default mappings with Private-Use Area assignments.)
37 *
38 * Also, in the past, some aliases were set such that e.g. cp850 became an alias for ibm-858.
39 * This followed the practice of OS/2 that uses the old codepage number 850 for the new
40 * codepage 858, with the main difference being the additional Euro sign.
41 * However, we have documented that the "cp" prefix should be used for Microsoft-compatible
42 * codepages, and Microsoft Windows 2000's codepage 850 does not contain a Euro sign mapping.
43 * Therefore, cp850 must not support the Euro sign.
44 * In these cases, I have changed the codepage name here to point to a newer codepage with the
45 * Euro sign, using its new name.
46 * I could not find such "updates" for codepages 1362 and 1363 - we might want to supply them later.
