Invalid characters in File.ReadAllText

阅读更多关于 Invalid characters in File.ReadAllText

I'm calling File.ReadAllText() in a program designed to format some files that I have. Some of these files contain the ® (174) symbol. However, when the text is being read, the returned string contains � (65533) symbols where the ® (174) should be. What would cause this and how can I fix it? This is likely due to a mismatch in the Encoding . Use the ReadAllText overload which allows you to specify the proper Encoding to use when reading the file. The default overload will assume UTF-8 unless it can detect UTF-32. Any other encoding will come through incorrectly. David Most likely the file

We've got a client who want's to superscript to "registered trademark" (®) character across their website. The website is CMS based and not only are they having trouble consistently superscripting characters but the superscript styling doesn't carry across to any CMS generated page titles etc. I'm wondering what are the possible/ best ways to achieve this: Can CSS be used to apply a style to a specific special character?

I know there are tons of threads regarding this issue but I have not managed to find one which solves my problem. I am trying to print a string but when printed it doesn't show special characters (e.g. æ, ø, å, ö and ü). When I print the string using repr() this is what I get: u'Von D\xc3\xbc' and u'\xc3\x96berg' Does anyone know how I can convert this to Von Dü and Öberg ? It's important to me that these characters are not ignored, e.g. myStr.encode("ascii", "ignore") . EDIT This is the code I use. I use BeautifulSoup to scrape a website. The contents of a cell ( <td> ) in a table ( <table> )

Regular Expression To Anglicize String Characters?

阅读更多关于 Regular Expression To Anglicize String Characters?

Is there a common regular expression that replaces all known special characters in non-English languages: é, ô, ç, etc. with English characters: e, o, c, etc. No, there is no such regex. Note that with a regex you "describe" a specific piece of text. A certain regex implementation might provide the possibility to do replacements using regex, but these replacements are usually only performed by a single replacement: not replace a with a' and b with b' etc. Perhaps the language you're working with has a method in its API to perform this kind of replacements, but it won't be using regex. ¡⅁uoɹʍ

问题 I am sent an XML string that I'm trying to parse via an XmlReader and I'm trying to strip out the \" characters. I've tried .Replace(@"\", "") .Replace("\\''", "''") .Replace("\\''", "\"") plus several other ways. Any ideas? 回答1: Were you trying it like this: string text = GetTextFromSomewhere(); text.Replace("\\", ""); text.Replace("\"", ""); ? If so, that's the problem - Replace doesn't change the original string, it returns a new string with the replacement performed... so you'd want:
