  20 /*
  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.
