Are there any heteronyms in English with different hyphenation patterns for line breaking? That is, is there any sequence of letters which can be interpreted as two different words with different pronunciations such that it would be generally considered appropriate to hyphenate at a particular point for line breaking only if one of the words was meant, not the other?
I’ve scanned through lists of heteronyms, but nothing’s popped out. As far as I know there are no reference works which address this question. The underlying question, I suppose, is whether it’s always possible to hyphenate purely mechanically, with a dictionary of hyphenations and without considering context.
Example from a comment: Suppose there were some word frochouse, which would be pronounced "fro-SHOOS" and could be hyphenated as fro-chouse, and another word frochouse which would be pronounced "FROCK-hows" and could be hyphenated as froc-house. That would be an example, if not for the fact that both are made-up words.
