    Yes, Windows fonts often have a Yen glyph for the backslash (U+005C) character.

    Depends on which Java encoding you use. Some map byte 0x5C to the
    backslash, some to the Yen.

    Avoid literal non-ASCII characters in the source code, use \uhhhh
    instead (even if the \ looks like a Yen symbol). You will find out
    fast if javac's encoding interprets byte 0x5C as U+005C or U+00A5...
    if you get into trouble, change the encoding on the javac command
    line.
