ผมใช้ตัวอื่นอัพโหลดแล้วก็แสดงภาษาไทยได้นะครับ พอมาใ้ช้ swfupload แ้ล้วชื่อภาษาไทยหายไปเลย
ในทางปฏิบัติผมมักบอกเสมอว่า ไม่ควรอัปโหลดชื่อไฟล์ภาษาไทยครับ เพราะมันค่อนข้างความคุมยาก เนื่องจากการแสดงผลภาษาไทยนั้นมันขึ้นกับคุณสมบัติหลายประการ เช่น ชื่อไฟล์เป็น UTF-8 หรือ Ansi(Tis-620), Server อะไร Linux หรือ Windows,
Server รองรับชื่อไฟล์ชนิด UTF-8 หรือ Ansi, และสุดท้าย โปรแกรมที่ใช้อ่านไฟล์ File Browser (Web หรือ FTP ที่ใช้) รองรับภาษานั้นๆ หรือเปล่า
แล้วดูจากโค้ดแล้วสามารถแก้ไขให้อัพไปแล้วภาษาไทยไม่หายได้ไหม
คงไม่ได้มั้งครับ เพราะมันก็เป็นไปตามปกติ อย่างที่มันควรจะเป็น (โดยส่วนตัวเคยพยายามลองแก้ไขแล้ว แต่มีปัญหาว่า บาง Server ก็ใช้ได้ แต่ บาง Server ก็ไม่สามารถใช้งานได้ ถึงแม้จะเป็น linux เหมือนกัน)
