strcanon

For each character in @string, if the character is not in @valid_chars, replaces the character with @substitutor.

Modifies @string in place, and return @string itself, not a copy. The return value is to allow nesting such as:

g_ascii_strup (g_strcanon (str, "abc", '?'))

In order to modify a copy, you may use func@GLib.strdup:

reformatted = g_strcanon (g_strdup (const_str), "abc", '?');
…
g_free (reformatted);
