By the way, none of the OP's posts mention reading a fixed quantity (and none use the word byte). The very solution you were assisting with, head piped into wc, makes it clear that a fixed-size read is not part of the equation.

locale.conf

LOCALE.CONF(5)							    locale.conf 						    LOCALE.CONF(5)

NAME

       locale.conf - Configuration file for locale settings

SYNOPSIS

       /etc/locale.conf

DESCRIPTION

       The /etc/locale.conf file configures system-wide locale settings. It is read at early boot by systemd(1).

       The basic file format of locale.conf is a newline-separated list of environment-like shell-compatible variable assignments. It is possible
       to source the configuration from shell scripts, however, beyond mere variable assignments, no shell features are supported, allowing
       applications to read the file without implementing a shell compatible execution engine.

       Note that the kernel command line options locale.LANG=, locale.LANGUAGE=, locale.LC_CTYPE=, locale.LC_NUMERIC=, locale.LC_TIME=,
       locale.LC_COLLATE=, locale.LC_MONETARY=, locale.LC_MESSAGES=, locale.LC_PAPER=, locale.LC_NAME=, locale.LC_ADDRESS=, locale.LC_TELEPHONE=,
       locale.LC_MEASUREMENT=, locale.LC_IDENTIFICATION= may be used to override the locale settings at boot.

       The locale settings configured in /etc/locale.conf are system-wide and are inherited by every service or user, unless overridden or unset
       by individual programs or individual users.

       Depending on the operating system, other configuration files might be checked for locale configuration as well, however only as fallback.

       /etc/vconsole.conf is usually created and updated using systemd-localed.service(8).  localectl(1) may be used to alter the settings in this
       file during runtime from the command line. Use systemd-firstboot(1) to initialize them on mounted (but not booted) system images.

OPTIONS

       The following locale settings may be set using /etc/locale.conf: LANG=, LANGUAGE=, LC_CTYPE=, LC_NUMERIC=, LC_TIME=, LC_COLLATE=,
       LC_MONETARY=, LC_MESSAGES=, LC_PAPER=, LC_NAME=, LC_ADDRESS=, LC_TELEPHONE=, LC_MEASUREMENT=, LC_IDENTIFICATION=. Note that LC_ALL may not
       be configured in this file. For details about the meaning and semantics of these settings, refer to locale(7).

EXAMPLE

       Example 1. German locale with English messages

       /etc/locale.conf:

	   LANG=de_DE.UTF-8
	   LC_MESSAGES=en_US.UTF-8

SEE ALSO
