Why is it random? I set the font "courier new" and it's UTF-8 encoding.
i am a chinese mifans and I'm sorry that I can't change the software language.
I'm sorry about my poor english.

Instead "Connect to app to update", I want write "I like unicorns and teddy bears".
Like you can see, my new translation is more long than the original. Isn't a problem, I can write over the other languages translations :). Write only over the translations !

I understand you said that we can overwrite in usual the original english translations to a bit longer so it will take space from the next language translations, but i have a concern about the day names, because they are after each other (Mon, Tue, Wed, Thu, Fri, Sat, Sun).

What if the newly translated day names extends beyond their own space? I mean in Hungarian, the Monday is "Hétfő", which has 2 accented letter. Its shortened version could be "Hét" or "Hé"(or even be "H"). But because of the accented letter "é", it will take at least 2 character and with the initial H it's already 3 character, then comes the closing "0x00" character. So i can't use the "Hét" form, or it's not a problem, just after its end, it should be there the closing "0x00"?

So my question is, could it be extended to take space(characters) from the next day name (Tue), or in this case, it shouldn't be longer than it's original length?

Thanks in advance for the answer/help.

You can't extend over a other English translation.
Also in Firmware weekdays are only for weather, for homescreen it's in Resources file ^^.

You have all characters displayed, all is good.
In your screenshot is functions, not translations.

i'm also working on this part on the same language and overall the translated text have similar length as the original english. of course it should be extended with some additional zeroes.

this should work, right?

Oh i see, thanks for the info.

If i want to have the watchface to be on the same language as in the firmware, i also have to modify(decompile and recompile) the appropriate resource file, and edit the english day names as pictures, right?

Last question then(i hope so, sorry for asking too much questions): So for a full language change, i also need a modified resource file(.res), not just the firmware file (.fw)?

Really thanks for your time and help.

Be aware about that Csü will take 4 characters and so, it will overlap to the original Fri string(Pé). Your 0x00 character will be shifted with one character to the right. So as far as i understand @MagicalUnicorn's explanation, because they're all english translations, they should be on the same space, shouldn't be moved away. (probably a pointer or array's address refers to that place and won't find it, or something like that)

Also Ke is shorter than Tue, so you should use two 0x00 characters at the end(just in case, shorter maybe not a problem, but better to be sure).

this overlapping thing is still confusing since you can overlap another languages but that's not clear what things are allowed in this case. hex editing is a mystery in some ways. but yes that edit is wrong. by following the rules the code should be looks like this:

Yes you need modify the Resources file, else weekdays on the homescreen will be in English.

(just in case, shorter maybe not a problem, but better to be sure).
Yes ^^.

In Black & Bold : Where you put 0x00 bytes.
In

@MagicalUnicorn Thank you, i really appreciate it, helped me a lot to find all of the strings.

Though i could find some minor mistakes in it (mostly spelling/typo). Also found a missing string.

Between Battery and Distance, Burned is missing.
Time is to short to be recorded -> Time is too short to be recorded
Distance is to short to be recorded -> Distance is too short to be recorded
Pace is to low -> Pace is too low
Before notification and notifications, there is also an extra space. -> _notification, _notifications
Found device, ring now -> Found device, ringing now
Press & holdto hang up -> Press & hold to hang up

Couldn't -> Couldn't update (it's not your mistake, it's literally just Couldn't, but i translated the original german string nearest to it, and its meaning is Update failed, which is quite the same as Couldn't update)
They messed it up after a firmware update probably. I have completed mine the same way as it would be a bit longer traslation.

PS: @MagicalUnicorn as i said, it helped me a lot, so don't take this as a criticism, just trying to help. Maybe someone will need it, who can't speak english well. Thanks again
