描述

From @Tratcher on Tuesday, August 26, 2014 12:32:12 PM

src/Microsoft.AspNet.WebUtilities/ParsingHelpers.cs has at least one place where it calls char.IsWhiteSpace, but this allows many strange Unicode characters. Review this parsing code and update it to be more accurate.

Copied from original issue: aspnet/HttpAbstractions#119

研究方向
The issue points to src/Microsoft.AspNet.WebUtilities/ParsingHelpers.cs where char.IsWhiteSpace is used. Research which Unicode whitespace characters are valid in form parsing (e.g., RFC 1866) and propose a constrained set. Check if the issue is still relevant given the repo's age; the file path may have changed in the current dotnet/aspnetcore tree. No linked PRs or assignees exist, so the fix is open.
