Title: sending UTF8
Post by: wbtcpip on May 12, 2023, 08:33:55 am

could you please confirm me if all RDS PIRA encoder models accept UTF8 characters in DPS1= DPS2= RT1= and RT2= commands? both via USB/COM or TCP?

If not, could you please tell me which models expect UTF8 charcaters and and which not?

thank you

All current PIRA models (excl. PIRA32) accept UTF-8 via the XCMD= command:

RT1:

Code: [Select]

XCMD=<rds><item><text>The RT here incl. řščěřžčžř and other extended characters</text></item></rds>
PS:

Code: [Select]

XCMD=<rds><exe>PS=řščžř</exe></rds>
etc.

Notes:
The receivers do not support UTF-8 via RDS and no such support is defined in currently applied RDS/RBDS standards.
The encoder or its control software internally convert UTF-8 to 8-bit EBU Latin code page.
The ability to show the extended characters depends on whether the character is convertible to EBU Latin code page.

ok thank you. For PIRA32 i'm cuurrently sending windows-1250 characters https://learn.microsoft.com/en-us/windows/win32/intl/code-page-identifiers and apparently it works. It's more safe if i send 20127 us-ascii US-ASCII (7-bit) ?  (i'm using WideCharToMultiByte api call inside my application)

I've sent the conversion table to your email.
First word is the EBU Latin character (128-255), next three words are appropriate Unicode characters in hex representation. 0 means unused position.
