Fgselectiveallnonenglishbin -

| Aspect | Implication | |--------|--------------| | All non-English | Potentially large memory footprint if input is huge. Streaming recommended. | | Language detection | High CPU cost. Use fast models (e.g., fasttext-langdetect, cld3). | | Binary output | Reduces storage compared to text, but not human-readable. Use schema versioning. |

Use langdetect or fasttext to identify non‑English text.

from langdetect import detect, LangDetectException
def is_english(text):
try:
return detect(text) == 'en'
except LangDetectException:
return False  # unidentifiable -> treat as non-english for safety

Create a binning function that separates English from non‑English and writes the latter to a binary file.

import struct
import pickle
def fg_selective_all_nonenglish_bin(input_texts, bin_file_path="nonenglish.bin"):
"""
Foreground, selective process: moves all non-English strings into a binary bin.
"""
non_english_items = []
for text in input_texts:
if not is_english(text):
non_english_items.append(text)
# Serialize to binary (e.g., using pickle or custom binary format)
with open(bin_file_path, "wb") as bin_f:
    pickle.dump(non_english_items, bin_f)
print(f"Binned len(non_english_items) non-English items to bin_file_path")
return non_english_items

Given the ambiguous nature of fgselectiveallnonenglishbin, here are two other possible meanings:

| Component | Alternate Meaning | |-----------|------------------| | fg | “Fuzzy grep” – a selective pattern matcher | | selective | Not all non‑English, but those matching a regex | | all | Across all input streams | | nonenglish | Characters outside ASCII (e.g., Unicode > U+007F) | | bin | Destination directory or binary decision (0/1) | fgselectiveallnonenglishbin

In that alternate world, the flag would:
“For fuzzy grep, selectively (using a threshold) decide for all characters whether each is non‑ASCII; output binary flags.”

But the most practical and common interpretation remains the language‑based sorting into a binary container.
