[eSpeak] Missing Zh-Yue in 3.0 RC about eyes-free HOT 6 OPEN

Which product is this bug report for?

Hello, I am the contributor of eSpeak Cantonese. Some dictionaries are missing 
in the standard version of eSpeak because of their big size. This dictionaries 
includes Russian, Cantonese and full version of Mandarin Chinese. I think this 
is the cause of the issue. Get those dictionaries and rebuild eSpeak should 
solve the problem. Let me know if I can provide help.

Can't bundle additional dictionaries due to size constraints, need to add 
interface for downloading additional languages.

I can reproduce the issue in eSpeak v1.46.02_r7 (both release version and debug 
version I built from source with Cantonese dictionary data). So it's NOT only a 
DICTIONARY MISSING issue.

When I switch to Chinese (YUE), which is Cantonese. Contry code HKG seems not 
pass into eSpeak Engine.

When I play sample text, Android TTS system seems not pass HKG contry code to 
eSpeak Engine too.

I have read source code of eSpeak Engine and found no clue. Is it because 
Android don't support country code of HKG? Any suggestion?

Thanks a lot!

Here are some code from com_google_espeakengine.cpp for reference:
const char *eSpeakSupportedVoices[][3] = {
        {"zh",     "zho",        "Chinese (Mandarin)"},
        {"zh-yue", "zho-HKG",    "Chinese (Cantonese)"},
