The diacritics are generally regarded as one sign consisting of a basic sign and a diacritic. If the diacritics exist as a single character, the appropriate code point from the standardized coding tables (Unicode) is used. If no Unicode decoding is available as a single character, a character combination is realized by using the Unicode entities from the Combining Diacritical Marks Unicode block, e.g. the superscript o over u or U (ͦ, U+0366;, COMBINING LATIN SMALL LETTER O).

When using combinable characters, write the basic character followed "seamlessly" by the diacritic. (e.g. uͦuͦ).

The spelling for the c-Cedille (ç, U+00E7, LATIN SMALL LETTER C WITH CEDILLA), the e caudata (ę, U+0119;, LATIN SMALL LETTER E WITH OGONEK) in the meaning ae or the e with trema (ë, U+00EB;, LATIN SMALL LETTER E WITH DIAERESIS) is done without the Combining Diacritical Marks.

The transcription is based on the German or Latin character set. Characters of other alphabets (Greek, Cyrillic, Hebrew, etc.) are realized using their corresponding Unicode Encoding.
