gchar* gimp_any_to_utf8 (const gchar *str, gssize len, const gchar *warning_format, ...);
This function takes any string (UTF-8 or not) and always returns a valid UTF-8 string.
If str is valid UTF-8, a copy of the string is returned.
If UTF-8 validation fails, g_locale_to_utf8() is tried and if it succeeds the resulting string is returned.
Otherwise, the portion of str that is UTF-8, concatenated with "(invalid UTF-8 string)" is returned. If not even the start of str is valid UTF-8, only "(invalid UTF-8 string)" is returned.
str : | The string to be converted to UTF-8. |
len : | The length of the string, or -1 if the string is nul-terminated. |
warning_format : | The message format for the warning message if conversion to UTF-8 fails. See the printf() documentation. |
... : | The parameters to insert into the format string. |
Returns : | The UTF-8 string as described above. |
const gchar* gimp_filename_to_utf8 (const gchar *filename);
Convert a filename in the filesystem's encoding to UTF-8 temporarily. The return value is a pointer to a string that is guaranteed to be valid only during the current iteration of the main loop or until the next call to gimp_filename_to_utf8().
The only purpose of this function is to provide an easy way to pass a filename in the filesystem encoding to a function that expects an UTF-8 encoded filename.
filename : | The filename to be converted to UTF-8. |
Returns : | A temporarily valid UTF-8 representation of filename. This string must not be changed or freed. |
gchar* gimp_utf8_strtrim (const gchar *str, gint max_chars);
Creates a (possibly trimmed) copy of str. The string is cut if it exceeds max_chars characters or on the first newline. The fact that the string was trimmed is indicated by appending an ellipsis.
str : | an UTF-8 encoded string (or NULL) |
max_chars : | the maximum number of characters before the string get trimmed |
Returns : | A (possibly trimmed) copy of str which should be freed using g_free() when it is not needed any longer. |
gchar* gimp_memsize_to_string (guint64 memsize);
This function returns a human readable, translated representation of the passed memsize. Large values are displayed using a reasonable memsize unit, e.g.: "345" becomes "345 Bytes", "4500" becomes "4.4 KB" and so on.
memsize : | A memory size in bytes. |
Returns : | A newly allocated human-readable, translated string. |
gchar* gimp_strip_uline (const gchar *str);
This function returns a copy of str stripped of underline characters. This comes in handy when needing to strip mnemonics from menu paths etc.
str : | Underline infested string (or NULL) |
Returns : | A (possibly stripped) copy of str which should be freed using g_free() when it is not needed any longer. |
