Wrong text encoding in cf-browser

[TarekkMA]

When I run mvn javafx:run on a macos I get the cf-browser window but with wrong character encoding.

I'm not too common to javafx, so I'm not sure, if I'm able to fix that at all ;-(.

Which java version do you use? java 8? java 11?
Which californium.tools version do you use 2.3.0?

[TarekkMA]

Thanks a lot for your comment and your effort in this library.
I have used the master branch and this is the result of java --version

java 14.0.2 2020-07-14
Java(TM) SE Runtime Environment (build 14.0.2+12-46)
Java HotSpot(TM) 64-Bit Server VM (build 14.0.2+12-46, mixed mode, sharing)

I tried to find some hints about that effect, but they are rare :-).
One issue may be, that the "gui.fxml" is read in a different encoding.
In my opinion that should be not the case, because the xml itself contains the right encoding tag for UTF-8.
Anyway, I added the charset explicit to the FXMLLoader.
The changes are on master, please pull and build it locally.

javafx-actual-default-font

Reading articles like that makes me feel, that it may be also related to your OS.
So, do other applications show latin/ASCII characters?

[TarekkMA]

The same issue is happening. And this is the first time I come across this issue on macOS, but I noticed something when running mvn javafx:run, this line indicates that this is an issue with the font API or something

2020-09-02 11:40:56.442 java[9359:120193] CoreText note: Client requested name ".SFNS-Regular", it will get Times-Roman rather than the intended font. All system UI font access should be through proper APIs such as CTFontCreateUIFontForLanguage() or +[NSFont systemFontOfSize:].

This is also the full output of mvn javafx:run in case it helps

Font error on MACOS

Maybe you can check the example in that issue?

[boaks]

Just, if you're interested:

I spent some time into improve the cf-browser. It supports now also observe/notify, a menu, to select some CoAP message details, and a view with connection details.
Feedback will be welcome.

[TarekkMA]

Wow, you are awesome. I was planning to add that myself but in my project we decided to leave CoAP for now.

Thank you a lot for this grate addition. CoAP don't have that much GUI tools that do work.

Font error on MACOS

Maybe you can check the example in that issue?

I know its been quite a while, I'm a student and not very experienced with javaFX and maven, but I have exactly the same issue Tarekk describes above. Same style characters appearing when trying to run through the terminal. If I run through my IDE IntelliJ, it runs with the correct encoding.

Was this a relatively simple fix? I have no idea whats wrong, but I get exactly the same error message mentioned in the "Font error on MACOS" article linked above.

I can confirm, this issue is not specific to only this application that I'm currently working on. If I try and run another application coded by someone else using maven, I get a similar incorrect encoding.

[boaks]

I'm also not too common with javaFX.

The issue here was caused using java 11 and the openJFX version. Updating the used version to 14 or newer helped. That is configured in pom.xml in the dependency of "org.openjfx:javafx-fxml"

<dependency>
	<groupId>org.openjfx</groupId>
	<artifactId>javafx-fxml</artifactId>
	<version>14</version>
</dependency>

With that, ensure you also use the "right java fx version" when run from the terminal

According the README, it's started with

java --module-path /usr/share/openjfx/lib --add-modules javafx.controls,javafx.fxml -jar cf-browser-2.5.0.jar 

I'm not sure, how you start it, but I would recommend to check the "--module-path".

Hope that helps.

As you know I had the same issue. After changing my dependencies related to javafx-graphics to 15 it solved the issue.

    <dependency>
      <groupId>org.openjfx</groupId>
      <artifactId>javafx-controls</artifactId>
      <version>11</version>
    </dependency>
    
    <dependency>
        <groupId>org.openjfx</groupId>
        <artifactId>javafx-media</artifactId>
        <version>11</version>
    </dependency>
    
    <dependency>
        <groupId>org.openjfx</groupId>
        <artifactId>javafx-graphics</artifactId>
        <version>15</version>
    </dependency>

    <dependency>
        <groupId>org.openjfx</groupId>
        <artifactId>javafx-fxml</artifactId>
        <version>11</version>
    </dependency>

[boaks]

Thanks for reporting that. Did you also check with 14? Or did you just use the "newest / 15"?

Uups, I saw it's javafx-graphics, not javafx-fxml
