Hi. I have a desktop app where I am working on a simple chat feature. The conversation is saved to MySQL server, and the desktop apps read/write to the server.
I am noticing on Mac, when there is a line return either by entering this in with the text or when coded as EndOfLine, it is displaying as several of the black diamonds with the question mark in the middle. Windows looks ok with the return.
Also, with the use of an apostrophe, Mac again shows several black diamonds, and Windows shows this:
hereÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢s the next line
When that should be “here’s the next line”
Is there a special trick to display these and any other special characters correctly?
e.g. with MySQLCommunityServer class you need to SQLExecute “SET NAMES utf8”.
Than all strings from MySQL need to use DefineEncoding to tell Xojo what encoding you use. Also all text going to MySQL need to go through ConvertEncoding to make sure it’s UTF-8.
Great thanks! I’ll give the page a read in a bit. That seemed to do the trick for the special characters, but the coded returns still show the diamonds on Mac. Is EndOfLine ok to use or should it be something like u&A
For example, I have the message area displaying with this:
That will tell Xojo that the string returned by MySQL is UTF8 encoded.[/quote]
Is this suggestion to add this during the save to the server of the message or during the display? It didn’t see to make any changes when made to the display into the TextArea. The user may enter in a carriage return in their message, so I’d like to have that covered if possible without showing the black diamonds
This seemed to work to remove the black diamond characters for the returns. However, I would still like to have some sort of carriage return. Below is the result using ReplaceLineEndings:

When I’d like it to look like:

And back to the special characters. On Windows, it seems to be acting well with the
db.SQLExecute("SET NAMES 'utf8'")
But here is the result on Mac:

The data on the server is displaying the apostrophe correctly
