illegal-characters

问题 Could someone provide (or point me to a list) of all the illegal characters in the XFS filesystem? I'm writing an app that needs to sanitize filenames. EDIT: Okay, so POSIX filesystems should allow all characters except the NUL character, forward slash, and the '.' and '..' filenames are reserved. All other exceptions are application-level. Thanks! 回答1: POSIX filesystems (including XFS) allow every character in file names, with the exception of NUL (0x00) and forward-slash (/; 0x2f). NUL

问题 this code basically reformats an xls file and saves it as an xlsx. however it uses G2 & H2 to grab the filename for the newly formatted file. So that means certain characters can't be in the file name. I added a chunk of code to replace those characters ( ' Remove/Replace Invalid File Name Characters WkbName = Range("H2") MyArray = Array("<", ">", "|", "/", "*", "\", ".", "?", """") For X = LBound(MyArray) To UBound(MyArray) WkbName = Replace(WkbName, MyArray(X), "_", 1) Next X 'MsgBox

问题 We are running into a problem when parsing emails with python from outlook. Sometimes emails have characters that are not able to be appended to an excel worksheet using openpyxl. The error it raises is just IllegalCharacterError . I am trying to force this to print out the actual characters that are considered "Illegal". That said while doing some digging in one of the files in opnepyxl I found on cell.py this line that raises the error. if next(ILLEGAL_CHARACTERS_RE.finditer(value), None):

问题 Is there a way to check if a String meant for a path has invalid characters, in .Net? I know I could iterate over each character in Path.InvalidPathChars to see if my String contained one, but I'd prefer a simple, perhaps more formal, solution. Is there one? I've found I still get an exception if I only check against Get Update: I've found GetInvalidPathChars does not cover every invalid path character. GetInvalidFileNameChars has 5 more, including '?', which I've come across. I'm going to

问题 I wanted to use StanfordCoreNLP library in my android app . So i have imported the .jar files using the following dependencies in my gradle.build file .

问题 I am using Path.Combine, and one of the strings contain a Unicode characters. I get {System.ArgumentException} exception; illegal characters in path. According to MSDN filepath/name can have unicode characters. Why do I get this exception? Edit: Here is the code: Path.Combine("C:\PDM\Silver","Amabel Bender QQQ") 回答1: I figured out the problem. The second string contains a "tab" character in it causing the exception. (that didn't showed up when I pasted the string here) Thanks everyone and

问题 Let's say I have the following data frame: a <- runif(10) dd <- as.data.frame(t(a)) names(dd) <- c("ID", "a", "a2", "b", "b2", "f", "XXX", "1", "4", "8") In dplyr , there is a nice way to select a number of columns. For example, to select the columns between column a and column f , I can use dd %>% dplyr::select(a:f) In my problem, the columns of the last part of the data frame may vary, yet they always have as name a number between 1 and 99. However, I can not seem to be able to do the same

问题 I am working on a form with the possiblity for the user to use illegal/special characters in the string that is to be submitted to the database. I want to escape/negate these characters in the string and have been using htmlspecialchars(). However, is there is a better/faster method? 回答1: If you submit this data to the database, please take a look at the escape functions for your database. That is, for MySQL there is mysql_real_escape_string. These escape functions take care of any characters
