à san tchèr content = having one’s fill of, as much as one likes

This expression turns up in a number of writings by George d’La Forge:

• …ch’est mangnifique dé pouver l’pâler à man tchèr content auve Madanme Triggs
• …eune nouvelle profêssion tchi pouôrrait m’empêchi d’viagi à man tchèr content
• Auprès tch’il’ eûdrent bu et mangi à lus tchèr content…
• A la pliaiche dé les laîssi mordre à lus tchèr content…

However it’s difficult to look up in the Dictionnaire Jersiais-Français – it’s not under content, and there’s no entry for tchèr. A version of this idiom is tucked away under tchoeu, but not precisely this form. It gives en aver san tchoeu content – with en aver san tchèr content as a Les Landes dialectal form. The meaning is evidently “to one’s heart’s content”.

Since tchoeu/tchèr is a dialectal difference, it should also be consultable under à san tchoeu content.
