What is the Difference Between Tilde Fonts and Bitstream Fonts?
Tilde signed a contract with Bitstream Inc.
in 1995. Since then Tilde localizes Bitstream fonts by adding special
characters for Eastern European, Baltic, Turkish and Cyrillic languages. Each
Tilde font pack contains fonts in PostScript and TrueType formats in various
encodings.
Although Tilde fonts have considerable
added value in comparison to the original Bitstream fonts, the price of
Latin-based fonts is the same as that of Bitstream fonts. Localized fonts with
Cyrillic alphabet price approx. 15% more.

What do I get in Tilde Fonts Package?
Windows Latin-based font pack contains PostScript and TrueType
fonts for cp1257
(Baltic), PostScript and TrueType fonts for
cp1250 (Central European), and TrueType fonts in Unicode encoding covering Baltic, Central
European, Turkish and Western languages.
Windows Cyrillic font pack contains PostScript and TrueType fonts for cp1251
(Cyrillic), PostScript and TrueType fonts for
cp1257 (Baltic), PostScript and TrueType fonts for cp1250 (Central
European), and TrueType
fonts in Unicode encoding covering Baltic, Central European, Cyrillic, Turkish and
Western languages.
Macintosh Latin-based font pack contains
PostScript and TrueType fonts in Apple Central European (CE) encoding.
Macintosh Cyrillic font pack contains
PostScript and TrueType fonts in Apple Cyrillic encoding.

What standards and code tables do Tilde localized fonts
comply with? What languages do Tilde fonts cover?

Can I use Tilde Fonts in Windows 3.x?
The fonts do work on Windows 3.x. However, font Setup works on
Win 32 only. Purchase the regular font set and request a font pack
for Windows 3.x from Tilde.

Is Euro Character Included in Tilde Fonts?
Euro sign has been included in fonts for
Windows. Its code is 0x80 / 0128 in CE,
Baltic and Western
code tables and
0x88/0136 in Cyrillic code table, 0x20AC as a Unicode number. In most cases it
should be available from keyboard by pressing CTRL+ALT+E.
On the Macintosh, Euro is not part of Apple
Central European code table. Since Tilde fonts comply with industry standards,
Euro in not part of Apple CE fonts. Euro has been included Apple Cyrillic code
table lately with its code 0xFF it has replaced the old Currency sign. It has
not been added to Macintosh Cyrillic fonts, but it can be appended upon
request.

How do I Decide whether to use Fonts in PostScript or
TrueType Format?
TrueType fonts are supported by both
Macintosh and Windows operating system. It means you can install the fonts and
use them right away. Tilde recommends the use of TrueType fonts in MS Windows
because of benefits of large character set and Unicode support.
PostScript format is a preferred choice
when working with text in EPS images since PostScript fonts can be embedded in
EPS files. For long PostScript format was the only choice when working with
PostScript output devices such as RIPs, Imagesetters, etc. However, lately the
situation is changing and more print shops do not mind using TrueType fonts in
published documents. Since PostScript fonts can hold a code table of 256-characters,
the Unicode-related technologies do not work in Windows MS Office
applications, text is treated as symbols and it is not spelled. To use PostScript
fonts, the user needs a PostScript font rasterizer. In most cases Adobe Type
Manager known as ATM is used to render fonts on screen and on non-PostScript printers.

In MS Windows, what is the Difference between Unicode Fonts and non-Unicode
Fonts?
Until
recently fonts and applications used one byte to address
each character in a font. Thus no more than 256 characters could be addressed in
a font. You needed one font
for Russian language and another one for German or Czech language, for example.
Since the advent of Windows 95 and later
operating systems, fonts with extended character sets have been supported both
by the operating system and by applications. The newer MS Office applications
let you choose a font and switch the languages within the same font freely.
Other applications use fonts with 256 character code tables via virtual fonts
that Windows system created from Unicode fonts using font substitutions.

What are Font Substitutions?
In MS Windows, for the older applications
to access the large character sets of Unicode fonts, the operating system can
generate derivated fonts with 256-character code table from the large WGL4
Unicode fonts. For that to happen, font substitution records must be made for
each virtual font to be created. They are stored in [FontSubstitutes] group in
win.ini file or the system registry. E.g., a record
Swiss TL Cyr,204=Swiss TL,204
means that a Cyrillic font "Swiss TL Cyr"
will show up in the font list generated from the physical font Swiss TL.
At setup time font Tilde Fonts, if the user
chooses to install Unicode fonts, the setup wizard will make the user specify
which codepages he wants activated.
Beware: Windows 95 and Windows 98 keeps
font substitution records in win.ini file. Size of this file should not exceed
64 Kb, otherwise last font substitutions in the list will not work. Get
familiarized with the meaning of font substitution records and keep out the
records that you do not need.
