Detailed Description
Glib::ustring has much the same interface as std::string, but contains Unicode characters encoded as UTF-8.
- About UTF-8 and ASCII
- The standard character set ANSI_X3.4-1968 – more commonly known as ASCII – is a subset of UTF-8. So, if you want to, you can use Glib::ustring without even thinking about UTF-8.
- Whenever ASCII is mentioned in this manual, we mean the real ASCII (i.e. as defined in ANSI_X3.4-1968), which contains only 7-bit characters. Glib::ustring can not be used with ASCII-compatible extended 8-bit charsets like ISO-8859-1. It's a good idea to avoid string literals containing non-ASCII characters (e.g. German umlauts) in source code, or at least you should use UTF-8 literals.
- You can find a detailed UTF-8 and Unicode FAQ here: http://www.cl.cam.ac.uk/~mgk25/unicode.html
- Glib::ustring vs. std::string
- Glib::ustring has implicit type conversions to and from std::string. These conversions do not convert to/from the current locale (see Glib::locale_from_utf8() and Glib::locale_to_utf8() if you need that). You can always use std::string instead of Glib::ustring – however, using std::string with multi-byte characters is quite hard. For instance,
std::string::operator[]
might return a byte in the middle of a character, andstd::string::length()
returns the number of bytes rather than characters. So don't do that without a good reason.
- Many member functions and operators of Glib::ustring and Glib::ustring_Iterator assume that the string contains only valid UTF-8 data. If it does not, memory outside the bounds of the string can be accessed.
- In a perfect world the C++ Standard Library would contain a UTF-8 string class. Unfortunately, the C++98 standard doesn't mention UTF-8 at all. C++11 has UTF-8 literals but no UTF-8 string class. Note that std::wstring is not a UTF-8 string class because it contains only fixed-width characters (where width could be 32, 16, or even 8 bits).
- Glib::ustring and stream input/output
- The stream I/O operators, that is operator<<() and operator>>(), perform implicit charset conversion to/from the current locale. If that's not what you intended (e.g. when writing to a configuration file that should always be UTF-8 encoded) use ustring::raw() to override this behaviour.
- If you're using std::ostringstream to build strings for display in the user interface, you must convert the result back to UTF-8 as shown below: std::ostringstream output;output << percentage << " % done";label->set_text(Glib::locale_to_utf8(output.str()));
- Formatted output and internationalization
- The methods ustring::compose() and ustring::format() provide a convenient and powerful alternative to string streams, as shown in the example below. Refer to the method documentation of compose() and format() for details. using Glib::ustring;12, ustring::format(std::hex, 16));
- Implementation notes
- Glib::ustring does not inherit from std::string, because std::string was intended to be a final class. For instance, it does not have a virtual destructor. Also, a HAS-A relationship is more appropriate because ustring can't just enhance the std::string interface. Rather, it has to reimplement the interface so that all operations are based on characters instead of bytes.

ustring Glib::ustring::casefold | ( | ) | const |
Returns a caseless representation of the UTF-8 string. The resulting string doesn't correspond to any particular case, therefore the result is only useful to compare strings and should never be displayed to the user.
std::string Glib::ustring::casefold_collate_key | ( | ) | const |
Create a unique key for the UTF-8 string that can be used for caseless sorting. ustr.casefold_collate_key()
results in the same string as ustr.casefold().collate_key()
, but the former is likely more efficient.
void Glib::ustring::clear | ( | ) |
std::string Glib::ustring::collate_key | ( | ) | const |
Create a unique sorting key for the UTF-8 string. If you need to compare UTF-8 strings regularly, e.g. for sorted containers such as std::set<>
, you should consider creating a collate key first and compare this key instead of the actual string.
The ustring::compare() methods as well as the relational operators == != < > <= >=
are quite costly because they have to deal with Unicode and the collation rules defined by the current locale. Converting both operands to UCS-4 is just the first of several costly steps involved when comparing ustrings. So be careful.

inlinestatic |
Substitute placeholders in a format string with the referenced arguments. The template string should be in qt-format
, that is "%1"
, "%2"
, ..., "%9"
are used as placeholders and "%%"
denotes a literal "%"
. Substitutions may be reordered.
- Example:
- using Glib::ustring;const int percentage = 50;
- Parameters
-
fmt A template string in qt-format
.a1 The argument to substitute for "%1"
.
- Returns
- The substituted message string.
- Exceptions

Format the argument to its string representation. Applies the arguments in order to an std::wostringstream and returns the resulting string. I/O manipulators may also be used as arguments. This greatly simplifies the common task of converting a number to a string, as demonstrated by the example below. The format() methods can also be used in conjunction with compose() to facilitate localization of user-visible messages.
- Note
- The use of a wide character stream in the implementation of format() is almost completely transparent. However, one of the instances where the use of wide streams becomes visible is when the std::setfill() stream manipulator is used. In order for std::setfill() to work the argument must be of type
wchar_t
. This can be achieved by using theL
prefix with a character literal, as shown in the example.using Glib::ustring;// Insert leading zeroes to fill in at least six digits
- Parameters
-
a1 A streamable value or an I/O manipulator.
- Returns
- The string representation of the argument stream.

bool Glib::ustring::is_ascii | ( | ) | const |
Check whether the string is plain 7-bit ASCII.
- Unlike any other ustring method, is_ascii() is safe to use on invalid UTF-8 strings. If the string isn't valid UTF-8, it cannot be valid ASCII either, therefore is_ascii() will just return
false
then.

void Glib::ustring::swap | ( | ustring& | other | ) |
Swap contents with another string.
- Parameters
-
other String to swap with.
ustring Glib::ustring::uppercase | ( | ) | const |
Returns a new UTF-8 string with all characters characters converted to their uppercase equivalent, while honoring the current locale. The resulting string may change in the number of bytes as well as in the number of characters. For instance, the German sharp s "ß"
will be replaced by two characters "SS"
because there is no capital "ß"
.

Check whether the string is valid UTF-8.
bool Glib::ustring::validate | ( | const_iterator& | first_invalid | ) | const |
Check whether the string is valid UTF-8.
