How to turn off a checker for "Title seems unclear, is it a complete sentence?"

Suggest modification:

If title has >50% letters which are non-ASCII (and non-ASCII Latin Extended, which basically means code point > 255)…

Turn off rules related to English (e.g. complete sentence, all-caps etc.)

Because under such circumstances, it is highly likely that:

  1. The title is not in English
  2. The English letters used in the title are probably ID’s, model numbers, codes (e.g. stock code), abbrev, prefix, etc. that should be left as-is
  3. Applying English styling rules is a mistake

This can be simply done by:

  1. Define non-english if (ch > 255) / (Latin letters total count) > 1
  2. Do not apply prettify on non-english
  3. Do not apply seems_quiet on non-english
  4. Do not apply seems_pronounceable and seems_unpretentious on non-english because their punctuation may not be in the ASCII set (e.g. CJK punctuation are all > 255)
