I am using librets to retrieve data form my RETS Server. Somehow librets Encoding method is not working and I am receiving some weird characters in my output. I noticed characters like '’' is replaced with ’. I am unable to find a fix for librets so i decided to replace such garbage characeters with actual values after downloading data. What I need is a list of such garbage string and their equivalent characters. I googled for this but not found any resource. Can anyone point me to the list of such garbage letters and their actual values or a piece of code which can generate such letter.
thanx
Search for the term "UTF-8", because that's what you're seeing.
UTF-8 is a way of representing Unicode characters as a sequence of bytes. ("Unicode characters" are the full range of letters and symbols used all in human languages.) Typically, one Unicode character becomes 1, 2, or 3 bytes in UTF-8. When those bytes (numbers from 0 to 255) are displayed using the character set normally used by Windows, they appear as "garbage" -- in this case, 3 "garbage letters" which are really the 3 bytes of a UTF-8 encoding.
In your example, you started with the smart quote character ’. Its representation in Unicode is the number 8217, or U+2019 (2019 is the hexadecimal for 8217). (Search for "Unicode" for a complete list of Unicode characters and their numbers.) The UTF-8 representation of the number 8217 is the three byte sequence 226, 128, 153. And when you display those three bytes as characters, using the Windows "CP-1252" character encoding (the ordinary way of displaying text on Windows in the USA), they appear as ’. (Search for "CP-1252" to see a table of bytes and characters.)
I don't have any list for you. But you could make one if you wrote a program in a language that has built-in support for Unicode and UTF-8. All I can do is explain what you are seeing.
If there is a way to tell librets to use UTF-8 when downloading, that might automatically solve your problem. I don't know anything about librets, but now that you know the term "UTF-8" you might be able to make progress.
