    The ibm-943_P15A table in ICU's default data differs slightly from the
    Windows 932 conversion behavior. I seem to remember that some 7
    roundtrip mappings are different (out of more than 8000).

    In particular, IBM's Unicode conversion tables for "PC codepages"
    rotate some control codes as you showed. (Trying to map the 0x1A
    ctrl-Z to U+001C because DOS/Windows interpret 0x1A ctrl-Z as
    end-of-text-file.) These control characters are rarely used, so this
    difference is usually benign.

    The ICU collection of conversion tables includes "true" Windows
    tables. You can add them to your ICU distribution, or use them with
    ICU from your application data. See

    (Some of these are part of ICU's default data; we included those that
    did not have close matches among IBM tables.)

    The one on should match
    Windows XP conversion.
