Hi Jorge,

I'm pretty sure the problem happens because of the replacement for the cedilla you do. You're using UTF8 character in code so it gets translated to: https://www.fileformat.info/info/unicode/char/00e7/index.htm (0xC3 0xA7)

Please use "\xE7" instead, like I did in this piece of my code: https://github.com/bartoszbielawski/InfoClock/blob/master/src/LocalSensorTask.cpp#L53

Please let me know if this solved the problem for you.

Cheers, Bartosz

Hi Jorge,

I'm pretty sure the problem happens because of the replacement for the cedilla you do. You're using UTF8 character in code so it gets translated to: https://www.fileformat.info/info/unicode/char/00e7/index.htm (0xC3 0xA7)

Please use "\xE7" instead, like I did in this piece of my code: https://github.com/bartoszbielawski/InfoClock/blob/master/src/LocalSensorTask.cpp#L53

Please let me know if this solved the problem for you.

Cheers, Bartosz

font -> { 0x00, 0x00, 0x1E, 0x03, 0x03, 0x1E, 0x30, 0x1C}, // U+00E7 (c cedille) ...

   answer.replace("%7C","\|");
    answer.replace("%7D","\}");
    answer.replace("%E7","\xE7");

in the browser the character appears correctly but in the matrix it does not .. it appears empty in the position where it should appear.

note: sorry for my bad english

I'm pretty sure you are aware that the matrix doesn't care about letters. It just draws pixels. Put your cedilla in place of let's say letter "A" and check if it displays it then.

Can you show me (via a gist maybe) your current code?

hello first of all thanks for the support i'm new to these things .. i knew that but i don't know why i can't add more "symbols", here is my code..

when i put the ç in the position a, the ç appears correctly in the matrix

Since you're new let me show you: https://gist.github.com/

You paste your code there and just give me a link. Easier to read.

Now, look at your symbol table. It has a hole! After 0x7F you have 0xA1N and where's 0x8N and 0x9N. You're basically reaching beyond the table. The line:
int c = text[idx] - 32; Shifts all the codes by 32 (so the space is the first one), but does nothing for your hole.

Now, think about it and try to fix it. I know how, but you should find the solution yourself.
