| It can sometimes require a special purpose text editor to actually enter a Ctrl-A character into a text file. Some editors may require a special key sequence or use of a menu option to enter a Ctrl-A character into a file. The graphical representation of the character may be a happy face or any other non-alphanumeric symbol that the editor chooses to render to represent that character code. There are [[atcodes|@-Codes]] for the equivalent of many of the Ctrl-A codes, so may consider using them if they are more convenient for your text editor of choice. | It can sometimes require a special purpose text editor to actually enter a Ctrl-A character into a text file.

| In the ''[[custom:text.dat]]'' and possibly some other files (e.g. [[JavaScript]] and [[:util:Baja]] source files), Ctrl-A characters may be included by using the escape sequence ''\1'' rather than having to insert an actual control character into the file. | In the ''[[custom:text.dat]]'' and possibly some other files (e.g. [[JavaScript]] and [[:util:Baja]] source files), Ctrl-A characters may be included by using the escape sequence ''\1'' (or ''\x01'') rather than having to insert an actual control character into the file. |

| The [[util:ANS2ASC]] utility may be used to convert files encoded with ANSI X3.64 terminal escape sequences (e.g. ''*.ans'') into Ctrl-A encoded output and the [[util:ASC2ANS]] utility can be used to perform the opposite operation (useful for editing Ctrl-A encoded files (e.g. ''*.msg'' or ''*.asc'') with an //[[resource:ansi editors|ANSI-BBS screen editor]]//). | The [[util:ANS2ASC]] utility may be used to convert files encoded with ANSI X3.64 terminal escape sequences (e.g. ''*.ans'') into Ctrl-A encoded output and the [[util:ASC2ANS]] utility can be used to perform the opposite operation (useful for editing Ctrl-A encoded files (e.g. ''*.msg'' or ''*.asc'') with an //[[resource:ansi editors|ANSI-BBS screen editor]]//). |
