I have noticed that with Keepass2Android Offline 0.9.9 some unicode characters, used in Macedonian and Serbian language are not supported.
These are the letters:
Ђ (U+0402), ђ (U+0452), Ѕ (U+0405), ѕ (U+0455). 19Ј (U+0408), ј (U+0458), Љ (U+0409), љ (U+0459), Њ (U+040A), њ (U+045A), Ћ (U+040B), ћ (U+045B), Џ (U+040F), џ (U+045F).
