Error form occur one time. Cannot be found in 須摩提女經.

It is hard to trace this character from the currently available versions of 須摩提女經. The most likely location we think where this phrase originated is:
「爾時阿那邠池。先與女造十二種寶車。先以赤蓮華𮆕内摩尼覆外。黄金重布白銀羅絡。琥珀揚班珊瑚琉璃車𤦲。合雜馬瑙交間水精。鱗暉琉璃采飾。復以紫磨徘徊懸灑疊起。」 (T0128, 宋/元 version)

Anyways, the character is stable in 一切經音義, although with slightly different glyphs.

In comment #5660, should the context of the mentioned "⿰車𫟛" evidence be provided?
Additionally, are 佛説須摩提女經 and 須摩提女經 the same scripture?

Strange glyph, might be the variant of ⿰車覃.

Based on the evidence shown in #5660 (all showing an extra stroke, and 3rd evidence showing two extra strokes), I think that the rhs should be U+2E5C6 𮗆 (variant of 覃). Cf. rhs of U+2DB1E 𭬞 (⿰木⿱覀卑). Therefore I suggest to change glyph and IDS to ⿰車⿱覀卑.
