R：從一個字符串中刪除所有編碼的文本

Question

在R，我已內編碼的垃圾字符串，如

"based on the unique spectral \xfc\xbe\x8e\x93\xa0\xbc\xfc\xbe\x98\xa6\x90\xbc\xfc\xbe\x99\xa6\x8c\xbcfingerprints\xfc\xbe\x8e\x93\xa0\xbc of their biochemical composition" 

有一種簡單的方法來剝去編碼垃圾的字符串，不管是什麼垃圾是？

Answer 1

使用gsub

x <- "based on the unique spectral \xfc\xbe\x8e\x93\xa0\xbc\xfc\xbe\x98\xa6\x90\xbc\xfc\xbe\x99\xa6\x8c\xbcfingerprints\xfc\xbe\x8e\x93\xa0\xbc of their biochemical composition" 
gsub("[^[:print:]]", "", x) 
# [1] "based on the unique spectral fingerprints of their biochemical composition"
