Discards all pairs of sentences which can't be decoded by latin-1 encoder.
|
|
|
|
It aims to filter out sentences with rare unicode glyphs and pairs which
|
|
are most likely not valid English-German sentences.
|
|
|
|
Examples of discarded sentences:
|
|
|
|
✿★★★Hommage au king de la pop ★★★✿ ✿★★★Que son âme repos...
