Bloček - the world only DOS editor with Unicode support!
====================================================================================
             
1) THE FOREWORD
Bloček is a text editor for DOS with several unique features. Unlike most DOS editors, it works in graphic mode which brings many advantages. First of all, it is not limited to 256 characters of ASCII set like editors in text mode.
Bloček can work with Unicode files and use 65,536 characters of the Basic Multilingual Plane which is sufficient to nearly all present languages.
Besides that it still keeps the ability to work in the non-Unicode mode using the legacy DOS fonts from data files or using the hardware font the VGA graphic card efectively emulating the traditional text mode editors.
Bloček is also a image viewer which displays BMP, PCX, PNG, JPG and WMF vector files. In JPG files can show the EXIF tags and allows to copy the stored information to text window.
Bloček can open, display and edit many files simultaneously and can process very big files with very long lines. It uses mainly proportional fonts, but monospaced fonts are also available.
Other interesting features are advanced word wrapping in the text files, the ability to change interface language (at the moment, Czech, English, French, German, Russian and Turkish versions are available) and more.

2) FONTS AND KEYBOARD
Hence Blocek is the DOS editor, it tries to cooperate with DOS system settings and environment as much as possible.
By default (which can be changed), it loads the current DOS character set and uses the DOS keyboard driver and some tricks on using the DOS keyboard driver after changing to Unicode mode. However, except the default DOS keyboard driver, Blocek can use its own keyboard drivers. You can switch them anytime by clicking the language selector in the upper right corner of the screen (or pressing Alt+LShift).
For example, you have DOS set to Central European code page with the DOS keyboard driver set to Polish, but you need to write Russian text. In Blocek, you simply set the keyboard language to Russian and either switch the font to non-Unicode Cyrillic font or you convert the document to Unicode and you have all the Unicode characters available in the Basic Multilingual Plane.
The default fonts for Unicode and non-Unicode modes can be changed by editing the configuration file BLOCEK.CFG
For Unicode mode you can use the bundled fonts with extension UFN (located in the FONTY subdirectory). The default one is the file UNISMALL.UFN which is quite complete, but you can use other UFN fonts which currently contain much less characters.
For non-Unicode use the fonts with extensions CH or FN defining the codepage dependent charsets with 256 glyphs. Or you can use the current loaded VGA fonts used by DOS.


3) LIMITATIONS OF THE UNICODE SUPPORT
Bloček only supports the so-called Basic Multilingual Plane (BMP) from the Unicode standard which covers virtually all present languages, except some less frequent East Asian glyphs. The emoji pictures are currently not supported.
The combining diacritics are also not supported but it's not a big problem as the Unicode files usually use embedded diacritics. The only exception where it's missing are the emphasised Cyrillic chars (but they are used very rarely anyway)
All relevant standards for Unicode coding are supported: UTF-8, UTF-16 LE and UTF-16 BE.
The HTML Unicode representation is also supported, e.g. &#269; for „c with caron“


4) BLOCK OPERATIONS AND CLIPBOARDS
The block operations were reworked in the version 1.7. First of all, the text blocks can be selected not only in the edited text, but also in the single line input boxes or from most of the texts somewhere in GUI like in information windows.
The block can be selected in three ways
1)   By keyboard functions. For the keyboard shortcut, look below
2)   By dragging the mouse with pressed left button
3)   Go the some place of the text and press Shift+Left mouse button (LMB). The go to other place and again press the Shift+LMB. The space between these two locations will be selected as a block. (This mechanism only works in the edited text)

What you can do with selected blocks:
-    Delete them (CTRL-Del)
-    Use them as a scope for many search or conversion operations
-    Copy to clipboard and eventually paste somewhere
Most editors only use one clipboard. Bloček has seven independent clipboards. To copy to clipboard, press Ctrl+number 1-7 (it was inspired by Command & Conquer game) and the block will be copied to clipboard 1-7.
The upper line shows which clipboards are used in the menu. With Alt+number 1-9 you can paste defined clipboard in cursor position.
Or you can also click on clipboard indicators in the menu. However, this variant will only work on editing text – not from the information windows.


5) IMAGE VIEWER
Bloček is not only the text editor but also a picture viewer. It is possible to open several text editor and picture windows simultaneously and fluently switch among them. However, there's a limitation that Bloček runs in 16-bit colors, but most images in these days use 24-bit colors. So the color quality is reduced a little bit in the viewer. Also note that Bloček can only display the images but not modify them.
Which image formats Bloček can load:
BMP, PCX, GIF, PNG
JPG - even with EXIF tags. Bloček is able to show EXIF tags and copy the information to clipboard and edited text (I'm not aware of any other DOS program which knows the EXIF information)
WMF - still used but a little bit outdated vector format


6) CONFIGURATION
Bloček loads its configuration from two files: DEFAULT.CFG and BLOCEK.CFG
DEFAULT.CFG is a "factory setting" and shouldn't be changed. BLOCEK.CFG is user setting which has higher priority than the default one. In other words, if a variable is found in both files, the variant from BLOCEK.CFG will be used.
Only DEFAULT.CFG is included in the distribution archive, so getting a new version won't change your favourite setting. If Bloček is installed for the first time and BLOCEK.CFG is not present, it will be created from DEFAULT.CFG
If in future I add some new variables to DEFAULT.CFG, Bloček will detect it and copy this setting into BLOCEK.CFG. 


7) LOCALIZATION AND EXTENSIBILITY
All texts in Bloček will be loaded from files in the TRANSLAT subdirectory and are named BLOCEK1.xx and BLOCEK2.xx (where „xx“ is the language identifier). It allows you to use Bloček in various languages. Czech, English, French, German, Russian and Turkish languages are supported. Bloček is open source so feel free to create your own translations. The translation instructions can be found in the file \TRANSLAT\TRANSLAT.TXT
Other localization features are custom keyboard layouts and Unicode and non-Unicode conversion filters.
All files are in the JAZNAS and TBL subdirectories. Feel free to create your own keyboard layouts. You have to create a new .KBT file and store it in the JAZNAS subdirectory.
You can also create your own ASCII-Unicode conversion filters in .TBL format. They are already prepared for many languages but you can still need a filter between Unicode and some alternate non-Microsoft standard for extended ASCII. The description of the .TBL format and a small conversion utility for it is available in the TBL subdirectory.
And finally, you can define files with the A8T extension which is used to group alternate ASCII codings to one language. For example, Czech uses codepages 852 (MS-DOS), 1250 (Windows), ISO-8859-2 (Unix) and 895 („Kamenicti“ standard for DOS). The A8T can group these codings together to make the conversions easier between them.


8) TECHNICAL INFORMATION
The reasonable minimal hardware for running Bloček:
Pentium 100MHz, 16MB RAM, Graphic card with 1MB VRAM compatible with VESA VBE 1.2 and capable to run at least 800x600 16-bit, Mouse, DOS 5.0 or equivalent.
Bloček needs the 386 instruction set but supports MMX extensions when available. The 686 instructions are not used in the official builds. 
Bloček needs a DPMI server to handle extended memory. There’s a CWSDPMI r7 server bundled in Rayer’s modification (which disables VCPI), but you can use any other DPMI server (official CWSDPMI, HDPMI32,..). However, you should prefer some with disk swapping.
Bloček  can use the long file name services when available (e.g. under Windows 95 or with proper DOS driver)
This program was written and compiled in Free Pascal (http://www.freepascal.org)
(actualy used version 3.0.4, for GO32V2 /DOS/)
