Hello,

I found a strange bug in grep.
some Japanese runes does not match ‘[^0-9]’.

for example ‘ま' (307e) and ‘み’(307f).

unicode table from 3040 to 3090 is 
3040 ぀	3041 ぁ	3042 あ	3043 ぃ	3044 い	3045 ぅ	3046 う	3047 ぇ
3048 え	3049 ぉ	304a お	304b か	304c が	304d き	304e ぎ	304f く
3050 ぐ	3051 け	3052 げ	3053 こ	3054 ご	3055 さ	3056 ざ	3057 し
3058 じ	3059 す	305a ず	305b せ	305c ぜ	305d そ	305e ぞ	305f た
3060 だ	3061 ち	3062 ぢ	3063 っ	3064 つ	3065 づ	3066 て	3067 で
3068 と	3069 ど	306a な	306b に	306c ぬ	306d ね	306e の	306f は
3070 ば	3071 ぱ	3072 ひ	3073 び	3074 ぴ	3075 ふ	3076 ぶ	3077 ぷ
3078 へ	3079 べ	307a ぺ	307b ほ	307c ぼ	307d ぽ	307e ま	307f み
3080 む	3081 め	3082 も	3083 ゃ	3084 や	3085 ゅ	3086 ゆ	3087 ょ
3088 よ	3089 ら	308a り	308b る	308c れ	308d ろ	308e ゎ	308f わ
3090 ゐ

I tried some of them.
