TextAbstraction - Characters removed from the Latin script.

TextAbstraction - Characters removed from the Latin script.

* There are many characters in the range of the Latin script which are not
  considered part of it.
  It causes font selection issues if the default platform font is not a
  Latin font.

  i.e. -The default platform font is one that supports the Telugu script.
       -The text is "-- తెలుగు లిపి hello world".
       -The "-- " was asigned the LATIN, "తెలుగు లిపి " TELUGU and "hello world" LATIN.
       -The "--" is not really part of the Latin script.
       -The "--" is supported by the default platform font which is a Telugu font.
       -The Telugu font has been cached as a font that supports Latin but it doesn't.
       -The "hello world" will be shaped with the Telugu font which doesn't support the Latin script.
