Improve ENGLISH_COMPATIBLE

[wasertech]

Use:

uni2ascii -q wiki_fr_lower_accents.txt > wiki_fr_lower.txt

Instead of:

commonvoice-fr/DeepSpeech/fr/prepare_lm.sh

Line 19 in 5699e59

iconv -f UTF-8 -t ASCII//TRANSLIT//IGNORE < wiki_fr_lower_accents.txt > wiki_fr_lower.txt

https://billposer.org/Software/uni2ascii.html

Why?

I've dump Wikipedia in English to make a custom scorer.

Here is the result with iconv:

+ build_lm.sh
+ '[' 1 = 1 ']'

+ export LANG=en_US.UTF-8

iconv: illegal input sequence at position 26095

     {!} : Aborted

If the iconv route works with our old wiki dump for french, i'm sure if I do a new one now, chances are we'll also get an illegal input sequence.
