TIL that KDE silently replaces slashes in filenames with a fraction slash

TIL that KDE has a killer feature which will silently replace a / with a ⁄ (fraction slash) when you go Right Click -> Create New -> Text file...

// See https://api.kde.org/frameworks/kio/html/global_8cpp_source.html#l00141
KIOCORE_EXPORT QString KIO::encodeFileName(const QString &_str)
{
    QString str(_str);
    str.replace(QLatin1Char('/'), QChar(0x2044)); // "Fraction slash"
    return str;
