| The following table describes all terminal capabilities that are recognized by screen and are not in the termcap(5) manual. You can place these capabilities in your termcap entries (in ''/etc/termcap'') or use them with the commands ''termcap'', ''terminfo'', and ''termcapinfo'' in your screenrc files. It is often not possible to place these capabilities in the terminfo database. | The following table describes all terminal capabilities that are recognized by screen and are not in the termcap(5) manual.

| A <charset-mapping> tells screen how to map characters in font <designator> (’B’: Ascii, ’A’: UK, ’K’: german, etc.) to strings. Every <mapping> describes to what string a single character will be translated. A template mechanism is used, as most of the time the codes have a lot in common (for example strings to switch to and from another charset). Each occurrence of ''%'' in <template> gets substituted with the <template-arg> specified together with the character. If your strings are not similar at all, then use ''%'' as a template and place the full string in <template-arg>. A quoting mechanism was added to make it possible to use a real ''%''. The ''\'' character quotes the special characters ''\'', ''%'', and '',''. | A //<charset-mapping>// tells screen how to map characters in font //<designator>// ('B': ASCII, 'A': UK, 'K': german, etc.) to strings.

| This tells screen how to translate ISOlatin1 (charset 'B') upper case umlaut characters on a hp700 terminal that has a german charset. '\304' gets translated to '''\E(K[\E(B''' and so on. Note that this line gets parsed **three** times before the internal lookup table is built, therefore a lot of quoting is needed to create a single '\'. Another extension was added to allow more emulation: If a mapping translates the unquoted '%' char, it will be sent to the terminal whenever screen switches to the corresponding <designator>. In this special case the template is assumed to be just '%' because the charset switch sequence and the character mappings normally haven't much in common. | This tells screen how to translate ISOlatin1 (charset 'B') upper case umlaut characters on a hp700 terminal that has a german charset.
