BSSScribe, aka “Black Speech School's (trans)scriber”, is the official transcriber of Nûrlâm dialect into Tengwar or Cirth available at http://blackspeech.ru/transcriber.

There are already many transcribers available, but none of them correspond to description of Black Speech mode at Amanye Tenceli or do not have it at all. Glǽmscribe is close to perfection, but for some reason it uses Quenya mode for diphtongs in Black Speech.

While the default font for now is Tengwar Artano, author of BSSScribe still prefers legacy Daniel Smith's encoding for these reasons:

• There are more fonts available for it;
• There are two concurring Unicode proposals, both not approved for 15+ years;
• Wikipedia articles provides older and obsolete one character map, not supported by currently popular fonts; e.g. articles say character U+E018 is used for “rómen” (1993 proposal) but it's mapped to “extended tinco” (2001 proposal) in majority of fonts;
• Unicode proposals have limited number of characters and their variants (e.g. no s-hooks), compared to Daniel Smith's version. Some existing fonts have these additional symbols, but their encoding is not standartized;
• Some Unicode fonts require additional third-party library to work as intended, as the result export as text will be useless;

Please note, that text for transcription should be spelled correctly according to chosen language. Any inappropriate characters will be encoded wrong or skipped. For example, this tool will not convert Qenya “k” to Late Quenya “c”, so the result with Qenya may be wrong.

• Whitespaces are ignored, but you can use underscore ( _ ) or non-breakable space (Alt + 0160) to force a space;
• Apostrophe ( ' ) is treated as glottal stop in Tengwar Black Speech mode;
• Diaresis over vowels in Tengwar Beleriand mode forces overdot, “ ï ” also forces a long carrier with overdot;
• Symbols “~” and “%” may be used to force “S-hooks” (unvoiced and voiced respectively) in Tengwar (only if option for automatic placing of S-hooks is turned off);
• Symbols “>” and “<” may be used as start and end text markers, as in Ring Inscription;
• Symbols “@” and “|” force “ossë” and “halla” in Quenya mode;
• Only decimal numbers are accepted (no automatic re-basing to duodecimal system);
• Symbol “\” may be used in any tengwar mode to “escape” the following character – it will remain the same in Dan Smith's encoding – use to insert additional tengwar unknown to BSSScribe;
• BSSScribe supports (experimentally) “raw-tengwar” syntax compatible with Glǽmscribe, Tecendil but with some extensions (full list will be published later after proper testing);
• Symbols “|” and “_” may be used in English mode to imitate J.R.R. Tolkien's writing, e.g. “here|in”, “of_the”, “and|e” to render as in DTS 5 (97RË5%, W:, 2P#È accordingly).
• Symbols “*”, “%”, “[”, “]”, “{”, “}”, “=”, “`”, “~”, “/”, “|”, “\” are used for pseudo-graphics with Cirth Erebor fonts 1 and 2;
• Cyrillic mode of Tengwar is based on Benct Philip Jonsson proposal (Download PDF). Except “щ” in Russian is encoded with alternate tehtar “aha” A instead of “aha” with palatalization diacritics dÍ; rare reversed tehtar for nasalized vowels are encoded with combination of nasalization mark and regular tehtar with fonts that don't support reversed tehtar.

A minimalistic version of BSSScribe exists (mainly for embedding purposes).
