Convert Characters RRS feed

  • Question

  • Hi

    We have a website contact us form. Users from different countries provide information. For e,g. people in vietnam input values 

    and this is coming as Name. H� TRỌNG  ĐẠI

    I tried this app and it returns correct value  like "H� TRỌNG  ĐẠI".

    How can I do this in C# .net? I would like to remove that replacement character also.

  • Convert it to what? You are allowing users to enter information in their own language. You cannot auto-translate that to English if that is what you are looking for. There are third party services that can make a best guess estimate but they are in no way accurate.

    Note that the string you gave appears to be HTML encoded because you have Ọ which look like the hex code. To HTML decode use the HttpUtility.HtmlDecode method. This converts it back to Unicode but in whatever language they were using.

  • Hi myCrmGuy,

    Thank you for posting here.

    I  think HttpUtility.HtmlDecode is not a good choice.

    It can work well when decoding some common characters, but if it involves some small languages (Vietnamese, Greek, etc.), it often cannot recognize these special characters.

    I know this problem for some time, but so far, I still don't know how to solve this problem, if there is new progress, I will inform you immediately.

    Best Regards,
