Bug feedback: Garbled text for channel name and EPG

I'm using ProDVB 7.26.6 /w rtl2832u-r820t2 DVB-T TV tuner on Win10 /w touch screen in Taiwan.
When I setup and searched the tv channels, I found channel name also EPG (Electronic program guide) become garbled text and cannot read.
It should be the normal Chinese text but garbled.

Can you help to fix this issue?
