[UNDERTALE] is chara female or male

I also think Chara is male, since judging from the appearance, I see it as boy-like.

Chara is gender neutral, if you do the genocide route, it's up to the player.

I always kinda thought Chara was a female.

Chara is genderless, but this is where headcanons come in: some think of them as a girl, others as a boy, and others as ambiguous. There's no right or wrong, so feel free to choose whatever you like. ^^

It doesn't even matter, unless you're one of those people who say Chara is female, it gets annoying, jesus Christ.

I honestly think Chara acts like a male, but, they're genderless.

Chara is most likely a neutral gender, like Frisk. But that is up to the player since there is no real proof of the player nor Chara having a gender.

hard to tell eh! if he/she or wat?? eh!

According to the undertale wiki, "Chara looks strikingly similar to the protagonist, down to a "similar fashion sense," as said por Asriel, and just like the protagonist, has an ambiguous gender."
