Special Character on Android #72

Open jennifer-debug opened 3 years ago

jennifer-debug commented 3 years ago

Hi, I would like to insert some word with special characters from Danish : "å ø æ ".... When I tried to insert them they turn out like chinesse character. I guess I need to change the font or the Ascii table. However, for android I have only the choice with "roboto" font. Do you have any other suggestion? Best Jennifer.

Is it a character that it in an interface label (i.e. set in the interface editor), or is it something generated in Pure Data and setting an interface label dynamically?

This will be a dynamical label. This is very weird. Let me try to explain... I have this text file with Danish sentences (see attachment). I would like to replace the content of a label by each line of this text. First, I am defining a text (call here text Dag1.txt into text_test).

Then each I am going to press on my button, I will update a pointer, that will read the next line of the text and send to /myLabel. Everything works fine, except that some of the special danish letters æ ø å are sometimes shown correctly (like in hjemløs), and sometimes is transformed into some weird Chinese character like "mørk". This is weird, I have checked with an Hex editor, and those characters are coded in a similar way. It seems that the surrounding will trigger or not this strange behaviour. I am clueless. Thanks for your help

Hi

Question: how did you make the .mmp file (which editor, and did you then tweak the JSON characters by hand?)? And are you using it on iOS or Android?

Briefly, I assumed that users would only use ASCII characters, since that is all that Pure Data supports. I should not have made that assumption.

There is a lot going on here. Basically, every piece of software involved (PureData, the MacOS editor, the Java cross-platform editor, the iOS app, and the Android app) each handles non-ASCII character encodings differently.

PureData is one-byte-ber-character, which they say is ASCII-only, but it turns out it will properly handle the whole byte and display in Western ISO-Latin character set (which supports Danish characters, so they show up in PureData [text] objects and messages)

MacOS editor is ASCII-only when loading and saving projects. It will not save the MMP file if there are any non-ascii characters. It will attempt to load, but its internal encoding seems to get it wrong (shows a different Danish-looking character).

Java Editor will write based on the character contents, either ASCII or UTF-8. But when loading a label text, will add <?> character for non-ASCII

iOS app will fail to load an .mmp with non-ASCII characters

Android app seems to load the mmp, but display incorrectly, truncating strings when it received a non-ascii character.

I don't think there is anything you can do at this moment. I need to reconsider how to support another character encoding (and whether that should be UTF-8 vs something else). I need to see if this will break existing projects or not. This is a significant change.

Ok, thank. That makes sense. I will find another way. Thank you anyway for this great app, and your dedication to making it work. Best
