When handwriting English, I write z with a slash through it (Ƶ/ƶ) to distinguish it from 2. I'm wondering if there is analogous notation for highlighting a less-common pronunciation due to 多音字 ("heteronym"). For example, from CC-CEDICT...
好吃 (hǎochī): tasty / delicious
好吃 (hàochī): to be fond of eating / to be gluttonous
When handwriting, it would be nice to indicate to the reader the change in tone (and meaning) here.
Question: When handwriting, is there a standard way of indicating a less-common pronunciation due to 多音字?
