    <p>I have a problem with a string in C++ which has several words in Spanish. This means that I have a lot of words with accents and tildes. I want to replace them for their not accented counterparts. Example: I want to replace this word: "había" for habia. I tried replace it directly but with replace method of string class but I could not get that to work.</p> <p>I'm using this code:</p> <pre><code>for (it= dictionary.begin(); it != dictionary.end(); it++) { strMine=(it-&gt;first); found=toReplace.find_first_of(strMine); while (found!=std::string::npos) { strAux=(it-&gt;second); toReplace.erase(found,strMine.length()); toReplace.insert(found,strAux); found=toReplace.find_first_of(strMine,found+1); } } </code></pre> <p>Where <code>dictionary</code> is a map like this (with more entries):</p> <pre><code>dictionary.insert ( std::pair&lt;std::string,std::string&gt;("á","a") ); dictionary.insert ( std::pair&lt;std::string,std::string&gt;("é","e") ); dictionary.insert ( std::pair&lt;std::string,std::string&gt;("í","i") ); dictionary.insert ( std::pair&lt;std::string,std::string&gt;("ó","o") ); dictionary.insert ( std::pair&lt;std::string,std::string&gt;("ú","u") ); dictionary.insert ( std::pair&lt;std::string,std::string&gt;("ñ","n") ); </code></pre> <p>and <code>toReplace</code> strings is:</p> <pre><code>std::string toReplace="á-é-í-ó-ú-ñ-á-é-í-ó-ú-ñ"; </code></pre> <p>I obviously must be missing something. I can't figure it out. Is there any library I can use?.</p> <p>Thanks,</p>

    1. COYou should add the platform you are targeting (Windows, Linux, etc.), and the encoding you are targeting (UTF-8, UTF-16, whatever). For example, your "á" is glyph E1, which translates 'á' on USO-8859-1 char, L'á' on UTF-16 wchar_t, but "á" (yes, two chars) on UTF-8

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
