- Why is the Sterling currency symbol encoded by the MVC HtmlEncode?
MVC.net will accept most currency symbols, allowing them through the html encode process untouched. But the UK Sterling symbol £ is replaced with the html code :
£If you post
₠ ₡ ₢ ₣ ₤ ₥ ₦ ₧ ₨ ₩ ₪ ₫ € ₭ ₮ ₯ ₰ ₱ ₲ ₳ ₴ ₵ ₶ ₷ ₸ ₹ ₺ ₻ ₼ ₽ ₾ ₿ $ £it encodes to:
₠ ₡ ₢ ₣ ₤ ₥ ₦ ₧ ₨ ₩ ₪ ₫ € ₭ ₮ ₯ ₰ ₱ ₲ ₳ ₴ ₵ ₶ ₷ ₸ ₹ ₺ ₻ ₼ ₽ ₾ ₿ $ £What is special about the £ symbol that requires it to be encoded when none of the others are? What security risk does this character present?
- How to decode diacritics in a string without allowing HTML using MVC5
Is there a framework supported way in MVC.net to decode diacritics in a textbox without just decoding the whole string and allowing HTML content?
If, the text box contains:
<b>Café<b>When re-rendering the page it becomes:
<b>Café</b>What is the correct way to allow these diacritics to display properly? using the inbuilt decode option results in:
Café
I could make a whitelist and convert these characters on the fly, but that seems clunky as I might miss some or allow potentially dangerous characters through by mistake. What is the recommended way to support these characters in MVC5?
- A potentially dangerous Request.Form value was detected from the client
Every time a user posts something containing
<or>in a page in my web application, I get this exception thrown.I don't want to go into the discussion about the smartness of throwing an exception or crashing an entire web application because somebody entered a character in a text box, but I am looking for an elegant way to handle this.
Trapping the exception and showing
An error has occurred please go back and re-type your entire form again, but this time please do not use <
doesn't seem professional enough to me.
Disabling post validation (
validateRequest="false") will definitely avoid this error, but it will leave the page vulnerable to a number of attacks.Ideally: When a post back occurs containing HTML restricted characters, that posted value in the Form collection will be automatically HTML encoded.So the
.Textproperty of my text-box will besomething & lt; html & gt;Is there a way I can do this from a handler?
