    Fix UTF-8 handling in incremental trace update API
    
    ## What does this MR do?
    
    This MR fixes invalid UTF-8 handling in incremental trace update API (used by GitLab Runner).
    
    ## Why was this MR needed?
    
    Current version is using `.length` method to determine current trace size where Runner is using the trace size in bytes. Also this byte size is used in headers and file operations to agree the trace part to send. This is a problem when build trace contains any multi-byte UTF-8 characters. This MR is fixing this situation so all parts are using the same size in bytes.
