I did not have the chance to test this for you. Reason being I am at work, but still here is a way you could do it.
Look at my method for the txt1 variable, it might be possible to make it better, but it should get the job done.

PHP код:

SendChatMessage(color,const txt[],const txt1[])
{
    for(new i=GetPlayerPoolSize()+1; --i!=-1;)
    {
        if(!IsPlayerConnected(i) || IsPlayerNPC(i)) 
            continue;
        new txt11[60], txt0[60]; pS[3] = {'!', ' ', ':'}, CharPos = -1;
        
       
        if(Chat[i])
        {
            if(strlen(txt1) > 100) 
            {
                for(new i; i++; i<sizeof(pS))
                {
                    //search for any characters nearby
                    CharPos = strfind(txt1, pS[i], true, pos=95) != -1) 
                        break; 
                }
                if(CharPos != -1)
                    //We've found a char that is defined in the pS array...
                    strmid(txt11, txt1, CharPos+1, strlen(txt1));
                else if(CharPos == -1)
                {
                    strmid(txt11, txt1, CharPos, strlen(txt1)); //no defined letters found
                    strins(txt1, "-", strlen(txt1)); //insert a letter to inform that word continues below
                }
            }
            //send the message
            SendClientMessage(i, color, txt1);
            
            if(strlen(txt11))
                SendClientMessage(i, color, txt11);
        }    
        else //do the same here with the other variable
        {
            SendClientMessage(i, color, txt);
            
            if(strlen(txt0)) //only send when there are contents in the var.
                SendClientMessage(i, color, txt0);
        }
    }
    return 1;
} 


Make sure to do the same for the remaining txt and txt0; as i defined.

Also, I think there was a limit of characters the client could send through the chatline, so at some point the text won't be longer than 144. https://sampforum.blast.hk/showthread.php?tid=404352
