L with bar should not be confused with Ł.
Ƚ (capital Ƚ, lower case ƚ) is a Latin letter L with a bar diacritic. It appears in the alphabet of the Venetian language, and in its capital form it is used in the Saanich orthography created by Dave Elliott in 1978.
In Unicode, both the capital and lower case are in the Latin Extended-B block.The capital is part of the "Additions for Sencoten" (Saanich), while the lower case is noted as an "Americanist phonetic usage" as an alternative to, the voiceless alveolar lateral fricative.[1]
