[solved] problem concatenating utf8string (sent with zmq)

[cpicanco]

Hi,

I am sending some strings such as:

ã, á, é

over the network using zeromq. Zeromq expects utf8strings. Typecast did not work:

UTF8string(ã)

Any suggestions on how to fix this??

PS.: Sorry, but this requires some clarification. The problem is nothing related to send-receive. Sorry again.

Hi,

I am sending some strings such as:

ã, á, é

over the network using zeromq. Zeromq expects utf8strings and everything is ok sending and receiving them. However, I think I am concatenating them wrongly:

Code: Pascal  [Select][+][-]

1. Caption := Utf8String1 +'ã';

Returns a caption with strange characters.

Any suggestions on how to fix this??

Edit.:

Found a solution:

Code: Pascal  [Select][+][-]

1.  Button1.Caption := Utf8String1+SysToUtf8('ã');

You forgot to mention your FPC and Lazarus versions.
The concatenation is correct if the encoding of Utf8ZMQString1 is UTF-8 and you use the new default UTF-8 system in Lazarus.
Please read this:

Thank you JuhaManninen. Will take a look. My actual version is 1.6. But I will move to 1.6.2 right now.

For string literals inside constants SystToUTF8 have no effect. So, issue persists, partially.

Further, with -FcUTF8, project will not compile with errors "string type expected" at chars such 'à' 'ã' 'é'.

In my case I am getting erros inside case statements.

Code: Pascal  [Select][+][-]

1. case S of
2.  
3. 'à' : Do something later;
4. 'ã' : Do it now;
5.  
6. end;
