Fix: Events callback, fix word length information for words with multibyte characters. Fix: Re-translating a word in a different language after the first langauge has started speaking individual letters, gave silence. Announce punctuation. If character name is not defined, use English. Announce punctuation. Fix pitch of the voice which announces punctuation characters. [[Phonemes]] text input. Allow the language-switch phoneme eg. [[_^_EN hEloU _^_FR]] in the input. git-svn-id: https://espeak.svn.sourceforge.net/svnroot/espeak/trunk@152 d46cf337-b52f-0410-862d-fd96e6ae7743
