| Keyboard hook conflicts | Intercepts WM_KEYDOWN globally; may conflict with modern IMEs (Google Input Tools, Microsoft Telugu IME) causing double typing. | High |
| Unicode normalization issues | Does not output NFC (Normalized Form Composed) consistently; produces NFD (Normalized Form Decomposed) for some conjuncts, breaking search/indexing. | High |
| No ARM64 support | Fails on Windows 11 ARM (Surface Pro X, new Macs with Parallels). | Medium |
| Abandonware risk | Last update was bug-fix only; no roadmap for OpenType feature support (e.g., vertical ligatures). | Medium |
| Security | Installs a kernel-level keyboard filter driver (ANUHook.sys). No CVEs reported, but closed-source. | Low-Medium |
Telugu, a Dravidian language spoken by over 85 million people, employs an abugida script where vowel signs modify base consonants. Unlike Latin scripts, Telugu requires complex glyph positioning, making font rendering non-trivial. Before OpenType and Unicode, proprietary font managers were necessary. Among them, Anu Script Manager became the de facto standard for Telugu desktop publishing (1998–2010). This paper updates its technical framework against modern standards. telugu fonts anu script manager updated

The updated software and its font packs are now widely distributed via digital download, moving away from the hardware-dongle (parallel port) protection schemes of the early 2000s. This has made the updated font libraries more accessible to freelance designers. | Medium | | Abandonware risk | Last
The digitization of the Telugu script has faced unique challenges due to its agglutinative nature, complex conjuncts (ottulu), and large character set. The Anu Script Manager (ASM), developed in the early 2000s, played a pivotal role in standardizing Telugu computing before Unicode became universal. This paper provides an updated analysis of Telugu font technologies, the architectural legacy of Anu Script Manager, and the transition to Unicode-compliant OpenType fonts. We examine current compatibility, migration challenges, and the relevance of ASM in preserving legacy documents.
