How to replace comma by slash using sed in an UTF8 file
Hello all,

I'd like to replace "," by "/" in a utf8 file from postion X to Y. Comma "," is also defined as delimiter.

12345678901234567890,123456789012345,12345678901234567890,
aaaa,aaaa,aaaaa ,bbb,bbbb,bbbbb ,cccccc,cc ,

Result should be
12345678901234567890,123456789012345,12345678901234567890,
aaaa/aaaa/aaaaa ,bbb/bbbb/bbbbb ,cccccc/cc ,

Example:
replace "," by "/" from postion 1 to 20
skip "," in the postion 21
replace "," by "/" from postion 22 to 35
skip "," in the postion 36
replace "," by "/" from postion 37 to 56
skip "," in the postion 57

Thank you for your support

tuned.conf

tuned.conf(5)						tuned.conf file format description					     tuned.conf(5)

NAME

       tuned.conf - Tuned profile definition

DESCRIPTION

       This  man  page	documents  format  of  Tuned 2.0 profile definition files. Profile is stored in /etc/tuned/<profile_name>/tuned.conf or in
       /usr/lib/tuned/<profile_name>/tuned.conf file where the /etc/tuned/ directory has higher priority.

       The tuned.conf configures the profile and it is in ini-file format.

MAIN SECTION

       The main section is called "[main]" and can contain following options:

       include=
	      Includes config file defined as value. Config file can be defined as full path or by the profile name to which it belongs.  If  this
	      parameter is present, the histogram will be shown at the end of the measurement.

PLUGINS

       Every  other section defines one plugin. The name of the section is used as name for the plugin and is used in logs to identify the plugin.
       There can be only one plugin of particular type tuning particular device. Conflicts are by default fixed by merging  the  options  of  both
       plugins together. This can be changed by "replace" option.

       Every plugin section can contain following sections:

       type=  Plugin type. Currently there are following plugins: disk, script, net, cpu, eeepc_she.

       devices=
	      Comma  separated	list of devices which should be tuned by this plugin instance.	If you omit this option, all found devices will be
	      tuned.

       replace=1
	      If there is conflict between two plugins (meaning two plugins of the same type are trying to configure the same devices),  then  the
	      plugin defined as last replaces all options defined by the previosly defined plugin.

       Plugins can also have plugin related options.

EXAMPLE

       [main]
       # Includes plugins defined in "included" profile.
       include=included

       # Define my_sysctl plugin
       [my_sysctl]
       type=sysctl
       # This plugin will replace any sysctl plugin defined in "included" profile
       replace=1
       # 256 KB default performs well experimentally.
       net.core.rmem_default = 262144
       net.core.wmem_default = 262144

       # Define my_script plugin
       # Both scripts (profile.sh from this profile and script from "included"
       # profile) will be run, because if there is no "replace=1" option the
       # default action is merge.
       [my_script]
       type=script
       script=profile.sh
