Reply To: How InDesign work with hyphenation?

Let's check those against dictionary.com (tiny disclaimer: this seems to be slightly biased towards US, not UK, English)

sin~~cere~~~ly > sin·cere·ly

ox~~~y~~gen > ox·y·gen

sep~~~a~~rate > sep·a·rate

in~~vin~~ci~~ble > in·vin·ci·ble

un~~e~~~ven > un·e·ven

… and this is from the online Help, on the use of tildes to indicate good/worse hyphenation points:

“If you don’t like the hyphenation points, follow these guidelines to indicate your preferred hyphenation of the word:

• Type one tilde (~) to indicate the best possible hyphenation points, or the only acceptable hyphenation point, in the word.

• Type two tildes (~~) to indicate your second choice.

• Type three tildes (~~~) to indicate a poor but acceptable hyphenation point.

• If you want the word never to be hyphenated, type a tilde before its first letter.”

So it would seem ID doesn't do too bad, and it's just a matter of personal preferences. Now those cannot be selected in ID's Preferences panel.

By the way, if your proofreader objects against 2 first or 2 last characters before/after a breaking point, you should change that in your Hyphenation settings. Those are there for exactly this reason.
