[TalkBack] Support entering of Germanumlauts and other special characters

[GoogleCodeExporter]

What steps will reproduce the problem?
1 In Jelly Bean, Settings, Languages and Input, Keyboard, add another keyboard 
language such as German.
2. Switch to that keyboard layout.
3. A way to enter umlauts is not possible. Sighted users tap and hold the u 
letter to get a selection of special characters such as ü, ú etc. TalkBack 
users cannot accomplish that.

What is the expected output? What do you see instead? There is no way to tap 
and hold a key. As soon as the finger is lifted, the letter is entered. There 
must be a way to turn the letter into "tap and hold" mode. In iOS, this is done 
by tapping the screen with a second finger while touching one of those keys, 
then lifting the finger to double-tap and hold to get the selection.

What version of the product are you using? On what operating system? TalkBack 
3.3.0 on Jelly Bean 4.2.2. Jelly Bean is the first Android version that works 
with the stock keyboard and does not require the Eyes-Free keyboard.

Please provide any additional information below.

Unfortunatelly this is not specific to german. It applies to most other 
languages besides english including spanish, french, italian, and also slavic 
languages such as slovak, czech, polish,. These are the languages where I know 
the alphabet. I am afraid there are many more languages where this is 
applicable thus if this can be addressed as soon as possible many many many 
people would get a chance to become more productive. Now the only workaround to 
type accented letters is by relying on auto correction what is not omniscient 
unfortunatelly.Enter your comments

En el idioma español no podemos escribir letras asentuadas, la única forma de 
hacerlo es buscando la palabra corregida.

d en el teclado español, los acentos no podemos hacerlos funcionar con Talk 
Back, sería bueno que nos diesen la opción de que Talk back verbalice cada 
acento y símbolos especiales.

The priority on this issue should be high. Not having accents and other special 
characters is like not having a complete alphabet as these characters affect 
meaning in languages that use them. Autocorrect catches most problems, but it 
misses a significant number (e.g., in Spanish words like "continúo," 
"continuo," and "continuó"). I don't feel that I can conduct work related 
communication on my device until this issue is fixed.
