Making OpenType fonts with free software
Bednár, Peter ; Mekyska, Jiří (referee) ; Rajmic, Pavel (advisor)
In thesis themes of typography and computer font of OpenType format is described in details. At the beginning attention is paid to historical development of typeface, where stress is laid mainly on development of Roman and white letter with their characteristics. Having presented basis of typography work is concentrated on topic of digital font with emphasis on possibilities of OpenType format. Further its characteristics and advantages were listed compared to another formats and it was evaluated as format appropriate also for creating font in education process. Letterspacing and kerning were mentioned between basic graphical modifications in creating fonts. In theoretical part of the thesis they were examined in available programs designed for creating font in OpenType format. Except free available means into summary were included also commercial types due to absence of more advanced instruments and functions with free available applications. In evaluation was found that the most convenient for education is Fontlab Fontographer commercial program, free Type lite and Fontforge indicated for Open-source platform. Practical part of the thesis is focused on two chosen programs for creating main font characteristics. The goal was to detect if it is possible to reach identical results when using both programs. Fontographer program enabled to use wide tool palette dedicated to vector graphic processing by means of Adobe Illustrator similar instrument. In the case of Type lite program there were rather less instruments, what is sufficient for elementary work and familiarization with creating of digital typeface. Freeware shortage is basic absence of kerning, spacing or hinting functions. Comparing program possibilities, it falls that freeware programs based on OS Windows with their functionality are sufficient only for entry level users. The best option within free available programs is Fontforge for OS Linux which supports mentioned typographic functions. Fontographer was recommended for teaching of basic characteristics of OpenType font format. Another goal of the thesis was creating of recommended work procedure for creating basic characteristics of OpenType font for students, that is enclosed at the end of the thesis.

Ehanced UNICODE Support for GNU Command Line Utilities
Oprala, Ondrej ; Smrčka, Aleš (referee) ; Peringer, Petr (advisor)
This thesis solves the problem of missing support for proper handling of Unicode input in the utilities of the coreutils project. Support was implemented for utilities cut, expand, fmt, fold, paste and unexpand. The implementation was done using the libunistring and gnulib libraries. Programs were properly tested and performance tests proved that performance is comparable or superior to the original implementation.

Písmová rodina Pagella: rozšírenie o skript Hangul
Hamarová, Lucia
This bachelor thesis is focused on the extension of the existing font family TeX Gyre Pagella with Korean glyphs defined by Unicode Hangul jamo blocks. In the theoretical part is initially discussed the issue of the Korean language and its alphabet – Hangul. Later, the concept of the font, its formats and their use in the TeX system is described. And last but not least is an analysis of the fonts available on the market. In the practical part is written the design and construction of characters together with a description of the font creation process in the FontForge program in the regular format. As a conclusion, there is a presentation of created characters divided into blocks Hangul Jamo, Hangul Jamo for Compatibility, Hangul Jamo Extended-A and Hangul Jamo Extended-B.

Regular expressions in programming languages
Benešová, Patricie ; Pavlíčková, Jarmila (advisor) ; Fortinová, Jana (referee)
The target of this thesis is to describe the usage of regular expressions in flavors of PCRE library and programming languages such as Java, Perl and Javascript and in Unix systems in languages AWK and GAWK and the grep program. The first part of this thesis deals with a general description of metacharactes, lookaround or Unicode properties used in regular expressions. The second part of this thesis is divided according to listed flavors. For every programming language or library there are specified supported options. Furthermore, there are examples of usage of regular expressions in the code of a given language. A separate chapter provides information about the Java flavor and an educational application in Java. The application can be used for trying out options described in this thesis and therefore it is set up especially for students. In the end, there is a comparison of all of the listed flavors and chosen syntax.

automatic recognition of encoding and language
Hron, Michal ; Pinkas, Otakar (advisor) ; Pavlíčková, Jarmila (referee)
Processing simple or complex texts (MIME type - application) often requires automatic recognition of encoding and language. Some types of files or pages contain an internal information about the encoding method. There might be some conflicts, however, eg. between the HTTP header and the meta tag. Sometimes it may be useful to verify the accuracy of the file encoding even when the encoding is known. In case that the identification of encoding is not available it is necessary to use a method of automatic recognition of encoding and language. One such method is an n-grams method. It has been used many times to categorize texts in many programs and in various programming languages. Based on tests results, it seems that the automatic recognition of the Czech language and other Slavic languages is less successful than the recognition of Western languages. Determining the reasons and searching for better solutions is therefore beneficial even nowadays. The length of the input text and the use of various languages in one document are important parameters. This thesis does not take text consisting of sentences in several different languages into consideration. In addition to a basic analysis of the topic, the thesis also includes a software solution to particular problems in a form of independent programs or plug-ins.
