I have a website which allows users to input usernames. 我有一个网站，允许用户输入用户名。

The problem here is that the code in c++ assumes the browser encoding is Western Europe and converts the string received from the username text box into unicode to compare with string stored within the databasse. 这里的问题是，c ++中的代码假定浏览器编码为西欧，并将从用户名文本框中接收的字符串转换为unicode，以便与存储在databasse中的字符串进行比较。

with the right browser encoding set the character úser is recieved as %FAser and coverted properly to úser within the program however with the browser settings set to UTF-8 the string is recieved as %C3%BAser and then converted to Ãºser due to the code converting C3 and BA as seperate characters. 在使用正确的浏览器编码集的情况下，字符úser被接收为％FAser，并在程序中正确地覆盖到úser ，但是在将浏览器设置为UTF-8的情况下，该字符串被接收为％C3％BAser，然后由于代码而转换为Ãser将C3和BA转换为单独的字符。

Is there a way to convert the example %c3%BA to ú while ensuring the right conversions are being made? 有没有办法在确保正确进行转换的情况下将示例％c3％BA转换为ú？

You can use the ICU library to convert between almost all usable encodings. 您可以使用ICU库在几乎所有可用编码之间进行转换。 This library also provides lots of string manipulation facilities. 该库还提供了许多字符串操作工具。
