Every character on Jiǎoluò Shūwū read as xue in any tone — 2 readings total across the four tones. Pick the tone you mean.
If you have the sound xue but not the character, here are the 2 characters read this way: 学 (xué, to study, to learn, learning), 雪 (xuě, snow, whiteness, and vengeance). They split across 2 tones, so the tone is what separates them.
