May need to use a single or double quote around the street name so that Waze understands that it's not an abbreviation that needs to be expanded.
We just need to decide on a standard to use and ensure the TTS acts as we expect.
For example: in centro/downtown Tijuana Mexico, some streets are named with a letter. On the physical street signs, the letter is in double quotes.
