57 * CommandLineToArgvW [SHELL32.@]
59 * We must interpret the quotes in the command line to rebuild the argv
60 * array correctly:
61 * - arguments are separated by spaces or tabs
62 * - quotes serve as optional argument delimiters
63 * '"a b"' -> 'a b'
64 * - escaped quotes must be converted back to '"'
65 * '\"' -> '"'
66 * - an odd number of '\'s followed by '"' correspond to half that number
67 * of '\' followed by a '"' (extension of the above)
68 * '\\\"' -> '\"'
69 * '\\\\\"' -> '\\"'
70 * - an even number of '\'s followed by a '"' correspond to half that number
71 * of '\', plus a regular quote serving as an argument delimiter (which
72 * means it does not appear in the result)
73 * 'a\\"b c"' -> 'a\b c'
74 * 'a\\\\"b c"' -> 'a\\b c'
75 * - '\' that are not followed by a '"' are copied literally
76 * 'a\b' -> 'a\b'
77 * 'a\\b' -> 'a\\b'
79 * Note:
80 * '\t' == 0x0009
81 * ' ' == 0x0020
