Best way to add accent to letter?

Question

I know the accent i want to add to the letter ex: "´" and i know the letter i want to add it to ex:"a", and i want the final result to be á. But this has to work with at least 5 letters: a,e,i,o,u AND 4 accent "´","","^","~".Right now i am working on a function with several diferentecase's`. Is there a better way to do this?

Method i am using right now: Letra: letter ; caraterEspecial: specialCharater

switch (caraterEspecial)
            {
                case "´":
                    switch (letra)
                    {
                        case "a":
                            letra= "á";
                            break;
                        case "e":
                            letra= "é";
                            break;
                        case "i":
                             letra= "í";
                            break;
                        case "o":
                             letra= "ó";
                            break;
                        case "u":
                             letra= "ú";
                            break;
                    }
                    break;

                case "`":
                    switch (letra)
                    {
                        case "a":
                            letra= "à";
                            break;
                        case "e":
                            letra= "è";
                            break;
                        case "i":
                            letra= "ì";
                            break;
                        case "o":
                            letra= "ò";
                            break;
                        case "u":

                    }
                    break;

                case "~":
                    switch (letra)
                    {

                    }
                    break;

                case "^":
                    switch (letra)
                    {

You can add a Unicode combining acute accent (U+0301). This will generate a 2-character sequence that is displayed as a character with accent.

If needed, you can normalize this string to a canonical form.

Ex.:

string s = "a";
s += "\u0301";
s = s.Normalize();

Note that this is still extremely culture specific, so it's not necessarily any better from simply having a dictionary for the mappings or something like that. Unicode tricks are fun, but different languages still treat similar concepts differently. – Luaan Apr 13 '16 at 15:01
When i try to use this code: http://www.fileformat.info/info/unicode/char/223c/index.htm They stay separated. How do i fix it? – meme Apr 13 '16 at 15:23
you have to watch out that you use _combining_ characters. combining tilde is U+0303 – king_nak Apr 13 '16 at 15:24

Easily you can use the replace method, but your question is incomplete. You should send the function , piece of code.

I would just use a s.replace('a','á'), maybe it's banal, but you don't have to deal too much, if letters are single like that.

That does not work because i need it for 5 letters and 4 accent. – meme Apr 13 '16 at 15:07
