About symbol sets
If you wish to extract readable text from a PCL file, it is essential that symbol sets are specified correctly. EscapeE interprets the characters in the original document using the symbol set defined on the General page of the Configuration dialog. Note that changing the 'source' will set up this symbol set automatically:
Source |
Typical symbolset |
Windows® driver |
HP3 - the character codes are adjusted by 3 so that a "D" in the file is translated to "A", etc. |
RedTitan DDF (PrePrinter) |
none - no translation is required. |
RedTitan Datastream Converter |
9700 |
Other |
(none) |
Custom PCL output (Source = Other) usually requires no translation but a few drivers require symbol set HP-1 (adds 1 to each code).
See also the Character recognition database Code tables.
When EscapeE extracts and outputs text, it can be set up to use a different symbolset. You may choose to use the standard Windows® character codes (19U), Unicode, or leave it Unchanged. |

Notes
Changing the symbol set may affect any data-fields and tags set up previously. See Field Problems.
Character recognition codes may be set up using EEfonts: choose Set up database for character recognition from the 'Fonts' menu.
EscapeE may be set to recognize the symbolset automatically by selecting <Auto> from the 'symbol set' list. This feature may be requested on the command line using the option:
