I think that I may have found a bug.
I wrote the following text in agora (286 characters):
After sending the message, it appears like this:
According to the counter under the text, I can write up to 1000 characters.
Noticing the last three characters of the cropped text, I assume that while submiting the greek characters are converted to HTML entity names (i.e. "ω" to &WCF_AMPERSANDω) and for this reason the entire text does not fit.
Does anyone else notice it?
