unsighed char数値をstringに変換

質問

unsigned char ch_name[18]

このように宣言した変数にバイナリファイルから読み取ったデータを入れて

ch_name[0] = 0x5f
ch_name[1] = 0x30
ch_name[2] = 0x61
ch_name[3] = 0x30
ch_name[4] = 0x64
ch_name[5] = 0x30
ch_name[6] = 0x66
ch_name[7] = 0x30
ch_name[8] = 0x68
ch_name[9] = 0x30
ch_name[10] = 0x73
ch_name[11] = 0x00
ch_name[12] = 0x74
ch_name[13] = 0x00
ch_name[14] = 0x75
ch_name[15] = 0x00
ch_name[16] = 0x76
ch_name[17] = 0x00

これらの数値はUnicodeで”たちつてとstuv”としてバイナリに入っていた文字列なのですが、これをString strにいれて”たちつてとstuv”として収納する方法はありませんでしょうか？
